Cleanout of Coal Mine Settling Ponds using TenCate Geotube® Dewatering Technology

 Cleanout of Coal Mine Settling Ponds A large Indonesian mining corporation operating an-open-pit coal mine in a remote part of South Kalimantan, Indonesia, faced a problem on how to dewater silt sediments from settling ponds that had reached their capacity. As part of the settling ponds cleanout efforts, a TenCate Geotube® dewatering facility was constructed to contain and dewater sediments extracted from the ponds. In total, more than 300 Geotube® dewatering tubes have been used to dewater more than 1,000,000 m3 of slurry containing 170,000 m³ of dry solids annually. To optimize land space the Geotube® dewatering tubes are stacked up to seven layers high based on standardized units with a circumference of 36.6m and lengths between 17.4m to 61.4m to create large solid landfill structures THE CHALLENGE The problem facing the mine was how to deal with high volumes of silt in evaporation ponds. The silt, originating from a mix of wastewater from the mines open pits as well as eroded silty rainwater runoff from within the mine catchment area, discharged into the ponds rapidly filling the header ponds before overflowing and clogging adjacent ponds. Initially, the problem was solved by constructing new ponds until there was a shortage of free land space. Cleaning the ponds required a constant combination of silt dredging and truck relocation in a constant cycle to prevent runoff with high levels of suspended solids (TSS) discharging into and polluting adjacent river channels. As silt levels in the ponds increased, the cost of dewatering ponds became prohibitive, requiring a more proactive and cost effective permanent Geotube® dewatering solution. THE DESIGN To prove the effectiveness and viability of TenCate Geotube® dewatering tubes, a series of on-site evaluation tests was undertaken. Firstly, a series of Rapid Dewatering Tests (RDT) was conducted to determine the most suitable polymer, the optimum polymer dosage and estimate the final end-of-dewatering solids concentration. Figure 1 and 2 shows the RDT test being undertaken and the effluent and dewatered solids captured. Secondly, a pilot tube trial was conducted using a few scaled-down Geotube® units that would simulate actual process conditions. The pilot trial validated the results of the RDT evaluation and was used to quantify information and operational implications that was then used in the final project design. Figure 3 shows the pilot trial set-up which utilized a Geotube® GT 500D fabric with a circumference of 13.7m and length of 30.6m. The pilot trial Geotube® units was laid out over a membrane lined platform to reduce ground infiltration of the effluent. The slurry pumped into the Geotube® units was dosed with polymer at the rate determined earlier by the RDT test. Figure 4 shows the final dewatered cake achieved in the pilot trial Geotube® units. THE CONSTRUCTION A Geotube® dewatering facility was constructed to contain and dewater slurry extracted from the ponds. Construction of the dewatering pad started in August 2015. Prior to placement of the Geotube® dewatering tubes, the surface area of the land was levelled and cleared of sharp objects such as rocks, roots etc as shown in Figure 5a. The pad preparation included the placement of a LDPE liner, drainage trenches, HDPE piping, manifolds and flexible hoses. A working space of about 5m was also allocated between the edge of the tubes and drainage for the operators as shown in Figure 5b. The first layer of Geotube® GT500D with a circumference of 36.6m and length of 61.4m was installed. Slurry was then pumped into the Geotube® dewatering tubes from a floating dredger in the ponds at a flow rate of 350-500 m³/hour in a 10-hour operation daily. The polymer used was a cationic flocculant injected at a dosage of 1.5 to 3.0 kg/MTds that was into the slurry prior to delivery into the Geotube® dewatering tubes. The maximum filled height was 2.65m and the final height after consolidation was 1.8m. After the initial Geotube® dewatering tubes have been consolidated, the following layer was then installed (Figure 5c). This process continued until seven layers of Geotube® dewatering tubes was installed. Effluent discharged from the Geotube® dewatering tubes was pumped back into the settling ponds. THE PERFORMANCE The Geotube® dewatering technology installed in this largescaled project has proven to be a highly effective and efficient solution with significant benefits in cost savings and environmental sustainability. The design of stacking seven layers of Geotube® dewatering tubes enabled land space to be well optimized while harnessing the performance of Geotube® technology. Geotube® dewatering technology improved the water discharge quality by substantially reducing the total suspended solids (TSS) being discharged back into the ponds with its ability of achieving high rates of solids retention and effluent discharge as compared to the previous dewatering methods used. The solids contained in the Geotube® dewatering tubes also eliminated the risk of rainfall erosion and silt runoff. Presently, the solids in the Geotube® dewatering tubes are being reclaimed as infrastructure earthworks fill, reducing carbon footprint while returning a revenue contribution to the mine operations. This project has the distinction of being one of the biggest Geotube® dewatering projects ever undertaken in the world providing a wealth of knowledge on the economics of extreme large scale Geotube® dewatering

Automated, Robotic Innovations for Analyzing Geological Samples with Portable XRF

​ By Todd Houlahan  Advances in robotics are leading to faster and more efficient X-ray fluorescence (XRF) analyses for geo-exploration projects. One new robotics innovation revolutionizing XRF analysis is GERDA, the automated Geochemical Research and Documentation Assistant. Created by the MEFFA Lab Oy in Finland, the automated unit is designed to test core in core boxes and soil, sediment, and crushed rock in plastics bags to achieve higher sample throughput with your portable XRF analyzer. The system is set up on a CNC table with a Vanta™ handheld XRF analyzer, a high-resolution USB camera, a simple control module based on Raspberry Pi 3, and easy-to-use software for visualization of results and data processing. In parallel with GERDA, the inventors have started to develop a unique method known as Nugget Effect Gold Assay (NEFFA) to estimate gold mineralization in samples (typically crushed rock or crushed drill core). Read on to learn more! GERDA is used with a Vanta XRF analyzer to automate testing for geoexploration projects. Developing the GERDA System The GERDA system was developed by a team that has been using portable XRF analyzers on mineral exploration projects for over 15 years. Largely focused on the use of pathfinder elements as part of their gold exploration projects, the inventors have witnessed the development of portable XRF analyzers over time, particularly the improvements in speed and the reduction in the test times required to achieve the levels of precision needed. They have also observed Olympus’ developments in detector technology and signal processing and, in particular, the Vanta analyzer’s ability to achieve lower limits of detection (LODs) of elements, including gold (Au). As junior explorers on a limited budget, their focus has been on greenfield exploration, rapid identification of anomalies, generation of drill targets, and potential new discoveries, not resource definition. Key to this has been their ability to test a far greater number of samples using their portable XRF analyzers than would be possible if all samples were assayed in the lab. GERDA is critical to their ability to do this. GERDA is designed to: Increase sample throughput for existing portable XRF owners Help select samples for more expensive laboratory assay Provide faster access to meaningful results for real-time follow up/infill Reduce the overall cost of exploration analytical budgets Make exploration programs more efficient To see how GERDA works with portable XRF, watch this quick video: https://www.youtube.com/watch?v=3-Gesp0Gjpk What is Nugget Effect Gold Assay (NEFFA)? To understand this new technique, it is important to know how the “nugget effect” works. The nugget effect is a term used to describe the sampling problem that can occur when there are large gold particles (nuggets) in a sample. If a nugget is selected during a traditional sampling process, researchers can overestimate the amount of gold in the sample. But if the nugget is missed, the gold can be underestimated. For gold exploration and mining, this variability can lead to inaccurate results and costly mistakes. The Nugget Effect Gold Assay (NEFFA) technique aims to turn the traditional challenge associated with the nugget effect into an opportunity. NEFFA attempts to measure the nugget effect through multiple nondestructive, systematic analyses of a geological material (typically crushed rock or crushed drill core) to identify the presence of gold or other precious metals based upon its distribution within the sample. NEFFA completely redefines and reduces the traditional sample preparation procedure and aims to provide semi-quantitative gold results using portable XRF analyzers to identify samples of potential interest for further laboratory analysis. Here’s how it works: Representative samples of 20–30 g, depending on the nature of material, are isolated in a medium such as a clear sample bag or under plastic film to ensure that there’s no contamination from an external agent The sample is distributed evenly over a 10 cm × 10 cm square with the depth of the material being no thicker than 2 mm A grid or matrix is placed over the sample, with individual matrices measuring 1 cm × 1 cm Measurements are performed within each square cm, and the average of all results is reported The technique is most effective on crushed rock or crushed drill core samples with a grain size 3 mm, but not on homogenized pulp samples Rotary air blast and reverse circulation (RC) samples can be analyzed directly This method takes the throughput advantages of GERDA for general exploration projects and adds additional value for gold exploration by providing gold estimates using XRF. We acknowledge this method may be considered non-traditional. Portable XRF’s weaknesses in analyzing gold are well known (elemental spectral overlaps can cause false positives, relatively high LODs compared to the lab, and fire assay is the best technique to use), however the inventors’ initial work using GERDA and NEFFA suggests meaningful gold data and cost savings are possible with this system. Also, local radiation safety and licensing requirements must be followed with any proposed implementation of this technique. By Todd Houlahan - Director, International Mining Group Todd graduated from the University of Newcastle, Australia in 1993 with a degree in soils and hydrology. For the past 18 years, Todd has been a leader in the portable XRF revolution in the mineral exploration and mining industries, publishing numerous papers on the subject and presenting at international conferences. For the past 10 years, Todd has led Olympus’ International Mining Group helping explorers, miners, and their shareholders achieve cost efficiencies by using the best portable XRF and XRD technology solutions.

From Educators to Licensed Professionals: TVIRD Scholars Make Waves in Their Chosen Fields

Photo Caption: Our future. Children study and play at the Canatuan Elementary and National High School – an institution that TVIRD helped build during its operations in the area from 2004-2014, and from which time the company has been the host municipality’s strongest partner in promoting responsive education. (TVIRD file photo) Siocon, Zamboanga del Norte / July 2021 – She knows what it is to be poor at a young age, being born to poor parents and raised by a single mother who died while she was in her primary years.  The harrowing experience of being bullied because of poverty made Joanamarie Gabayan vow to have a stable job in the future. At 19, she fulfilled her promise to herself and joined the academe where a decent, fulfilling and stable job as a professional teacher awaited her. Joanamarie, “Joan” to family and friends, earned her degree in elementary education in 2015.  She took and passed the professional board examination for teachers then and landed a teaching job the following year – thanks to the scholarship program of TVI Resource Development Philippines Inc. (TVIRD) in Canatuan. Now 25 years old and already married, Joan is currently teaching the Subanon children at Barangay Tabayo Elementary School of this town.  Assigned as an Indigenous People Education (IPEd) teacher by the Department of Education (DepEd), she instructs her pupils on basic education that is responsive to their context, respects their identities and promotes the values of their indigenous knowledge, skills and other aspects of their cultural heritage – all in line with DepEd Order 50 series of 2016. Looking back at her humble beginning, Joan said she is forever grateful to the company that helped her realize her dream. “I could not have reached this far without TVIRD,” she said. Giving back Police Corporal Rasul Agang, also a former scholar of the company agrees with her. A graduate of BS in Criminology at a state university in Siocon town, Corporal Agang is now proudly serving his “kababayans” as a member of the Siocon Police Station.  At 27, Rasul said he “walks the talk” of the PNP Motto which is to “Serve and protect.” A son of a fisherman, Rasul shared that ever since he was young, he wanted to become a police officer. “That was my dream, and I was able to achieve it through the help of the company.  I am always proud of being a scholar and part of the TVIRD family, knowing that it is a responsible mining company,” he said. Rasul cited TVIRD’s ongoing final mine rehabilitation in Canatuan, which started in 2016.  The program consists of “re-greening” and restoring the company’s former mine site to its former condition and covers all disturbed areas during its 10-year mining operations from 2004. Equally thankful is geologist-scholar Ryan Lumabi, also a Subanon from Sitio Canatuan.  Ryan currently works as a project geologist at Premium Megastructures Inc. in Misamis Oriental. “I just want to say thank you very much to TVIRD for making my dream possible.  It really was impossible for me to reach my dream given that we were poor.  But (they) gave me the opportunity to study and graduate as well as assisted me financially while taking the board examinations,” he said.  Investing in education “TVIRD believes that education plays a vital role in empowering its Subanon partners; hence, the company must invest on it,” according to TVIRD President Yulo Perez who was then Canatuan General Manager who institutionalized the company’s College Scholarship Program in early 2005. According to him the program seeks to provide the poor but deserving Subanons with access to education so they will be able to help the tribe’s elders in managing the development of their homeland – all according to their needs and outlook, and within their cultural and traditional framework. Also included in the grant were underprivileged but deserving non-tribal scholars residing within the immediate community and the host municipality of Siocon. From 2004 to 2020, TVIRD spent more than Php11-million pesos for its scholarship program.  The amount is on top of the construction cost of the first school buildings and library of Canatuan Elementary and National High School as well as the salaries of both school’s first four school teachers. TVIRD also provided school buses for the pupils and students of both schools. The first bus could accommodate 48 passengers and ferried the children as far as Sitio Kilometer 8, a sub-village of Kilalaban of the neighboring town of Baliguian, and Sitio Paduan of Barangay Candiz in Siocon town. When TVIRD concluded its Canatuan operations in 2014, it also produced professional teachers, nurses, midwives, civil engineers, agriculturists, geologists, an environmental engineer, a forester and a member of the Philippine Navy. Geologist Ryan Lumabi mentioned earlier that the education provided to him by the company gave him the fighting chance to reach his dream. “Mining may cease, and TVIRD may eventually leave Canatuan.  But the education it provided will live on in the hearts of its scholars whose lives were touched and changed for the better,” he concluded.

Geotechnical Investigation Approaches on Tailings Dams

​ Tailings dams are the most common means of waste disposal in the mining industry because of their ability to hold huge amounts of material, as well as cost effectiveness. Tailings dams can represent an ongoing liability, long after mine operations cease and facilities are closed and reclaimed. There is a global drive to ensure tailings dams are engineered during construction and evaluated for closure following the end of production. A tailings dam failure is defined as a physical breach of the dam followed by uncontrolled and typically sudden release of stored materials (e.g., fluids, tailings, sludge, etc.). There are several cases per year of significant failures, with many of these claiming lives. As an industry, we have a duty of care to improve approaches and ensure risks are lowered. Often complacency in operations and storage with an approach of “doing the minimum’’ is not the best practice, and every engineer and organization must do better to raise the bar and protect the lives and environments surrounding these often huge structures. In the Philippines, with our frequent and often severe earthquakes, tailings dams require robust engineering, high quality monitoring and civil, geotechnical and environmental engineering assessments to ensure the sites are stable long after a mine is a distant memory. Stability assessments referred to as a Tailings Dam Breach Analyses (TDBA) are a common approach to investigating tailings dams, and this requires detailed, high quality site investigation works. This is where RDCL provides various geotechnical and geophysics techniques that feed engineering data into ground models for breach analyses. The most common forms for geotechnical investigations are drilling and installation of ground water piezometers. RDCL takes intrusive testing beyond drilling with highly accurate Cone Penetrometer Testing (CPT) and seismic testing. The cone of the CPT rig is made up of load cells or pressure sensors, collecting a variety of data used directly in engineering calculations. CPT testing is calibrated to international standards, and is repeatable. The data is digital, and the quality control checks during testing removes the risk of collecting poor data, leading to poor engineering assumptions.  Do it right to design it right, remove the requirement for over-engineering which can lead to significant cost increases. RDCL operates GeoMil CPT rigs in Philippines and has tested to 68 m below ground in tailings dams. Typically, CPT tests reach depths of 20-30 m. In one day 6-8 CPT tests can be completed, pending site constraints. The CPT rig also has options to deploy seismic geophones, soil samplers and electronic shear vanes, all of which allow discreet soil testing at specific depths. These additional tools, all part of the Geomil suite of equipment allow in-situ measurements of soil characteristics targeting specific layers within tailings, often to determine liquefaction risk. RDCL often recommends more than CPT and drilling data across tailings dams, as both techniques are vertical datasets, effectively creating a series of pin-point datasets across often very large areas. This leads to interpolation between datasets, and generalization of ground features. Surface seismic testing can provide 2D profiles across tailing dams, linking drilling or CPT data creating with good visualizations improving the understanding of soil characteristics across sites. Two common seismic methods are used; MASW (Multi-channel Analysis of Surface Wave), deliver Shear wave (Vs) data SRT (Seismic Refraction Tomography), delivers compressional wave (Vp) data The deployment of surface seismic methods typically involving a long seismic array of 24 to 48 geophones in a straight line and seismic shots (mostly via a sledge hammer), which propagate along and through the ground generating profiles as shown in this article. Engineering modulus and Poission’s ratio are a common output from seismic surveys. And ground water levels are also derived, via the compressional wave velocity (Vp). A measure of 1500m/s Vp in soils indicates the soils are >99% saturated – and may be prone to liquefaction. Seismic Refraction Tomography (SRT) is a good way to define the saturation level of soils, 1500m/s Vp indicated >99% saturation. This provides are very useful “delineation” of where tailings materials may liquefy. This interface between dry and saturated tailings allows determination of groundwater level geometries. Multi-channel Analysis of Surface Waves (MASW) can provide information on the internal structure of enclosing material, as shown in the equations above. The Vs of soils increases as soil stiffness increases. A high Vs means a higher shear strength. When an earthquake shears the ground, soils with a low Vs are more prone to liquefy if they are silts and sands. In summary tailings dams are not naturally occurring, consolidated deposits. They are often accumulated in very short time scales and can be prone to failure. If Tailings dams are engineered, monitored and have robust testing techniques described here, we, as an industry, can lower the risk of catastrophic failures improving the lives of everyone involved working on them and living around them. ​

Geoscience Data Management in the age of Mine Digitalization

​ By: Engr. Jeffrey Geronimo Data remains one of the most important assets of any mining company – and for these to become assets, these must be accurate and reliable. Data drives mineral exploration and mining operations. However, with the sheer volume of data we obtain, no one would object that these are usually overwhelming to manage; from the location and geochemistry of every hand sample; to the structural-geochemical-geophysical information collected from the nth drill hole just to define the resource; and even up to the 4D mine model showing the depth, thickness, grade. Gathering geoscience data is crucial for a mining project. Millions of pesos are invested in the process of obtaining new and managing old data. New data brings fresh interpretations to keep mine models updated. Older data may increase in value as the degree of confidence becomes higher proven by the new data obtained.  In addition, discoveries and deeper understanding of the project are often attained by continuously reinterpreting data from the past. When effectively managed, geoscience datasets can be aggregated to generate subsurface and resource models that underpin critical financial and engineering decisions. THE BIGGEST CHALLENGES: DISCOVERY, ACCESSIBILITY, AND SHARING What data do we have? Where are these?  How do we access these? These are three of the biggest data management challenges faced by mining companies. In most instances, files are just locally stored on each of the user’s laptops or desktops with the occasional habit of backing it up via the company’s file server. Moreover, sharing of valuable company data is done by just using e-mails, flash drives, FTP servers or even just through social media platforms. All these methods provide limited traceability and will compromise data security. While the abovementioned file management styles can get the job done, these could eventually reduce business efficiency and lead to reduced productivity. Do we have the latest version of the drillhole data? What if I was basing my work on outdated data the whole time? Where was the document saved by my colleague prior to his leave of absence? It is a formula for disaster! Therefore, having a transparent process workflow can ensure geoscience data management be aligned and supported in mining projects. THE SOLUTION: STRATEGIC GEOLOGY MODELING Paramina Earth Technologies, Inc. is proud to bring the golden standard for geoscience data management.

LONG-COVID ANOTHER CHALLENGE FOR A SAFE WORKPLACE

By Dr Olivier Lo, Medical Director, International SOS & Rita Dayoub, Health Consultant, International SOS While most of the patients suffering from “acute” COVID-19 would recover fully in a maximum period a four weeks’ time, others will experience long-term after-effects. When existing symptoms may last longer than expected or new ones develop following the “acute” COVID-19 infection, we refer to “ongoing” symptomatic COVID-19 (from four to twelve weeks). In certain cases, this could also lead to more chronic conditions, usually identified as “Post COVID-19” syndrome (when signs and symptoms continue for more than twelve weeks). For simplicity, we will use “long-COVID” definition to describe signs and symptoms that continue to develop after “acute” COVID-19. It includes both “ongoing symptomatic” and “post-COVID-19” syndrome.  Even people who did not have symptoms when they were infected can have long-COVID. These conditions can have different types and combinations of health problems for different lengths of time. They can last for months and impact significantly both the physical and mental health of the patient as well as their ability to cope.  What should organisations consider managing return-to-work for long-COVID employees? How can employers ensure a safe work environment despite long-COVID risks? How can long-COVID impact employees’ productivity and business continuity? A variety of questions and doubts subsist for organisations on how to approach and manage effectively this emerging and concerning phenomenon.   HR preparedness & long absenteeism With this emerging concern around long-COVID, Human Resources professionals must be prepared to respond efficiently, both addressing long-COVID employee concerns and needs and ensuring a safe work environment for their overall workforce. Some preventive measures can be considered to help ensure a smooth return to work despite the long-COVID threat: Align your HR policies – Long-COVID can imply long-term absenteeism, resulting from the patient’s difficulty to cope. Hence long-term absenteeism needs to be covered in your HR policies with clear directions for such situations. Although is not a legal requirement yet to have it included as part of your official policies, this might evolve rapidly, varying from a country to another. Ensure to remain informed on the latest legal regulations and requirements on this matter to remain  compliant. Policies will need regular review and adaptation to reflect the latest evolvements. In a longer-term future, as we will learn more on long-COVID and its implications, this might be considered as a chronic condition for more serious cases and hence be formally included as such in the HR policies as any other disability or chronic disease. Consulting services will help you identify and adapt your current policies in place accordingly, to fully cover the challenges of long-COVID. Educate and communicate about long-COVID – Make sure your people are aware of the long-COVID condition and associated symptoms(1). This will help them to be diagnosed at an early stage. The education process could be implemented internally through email or other education material such as webinars. Talk to medical experts to get all the essential insights. Encourage your workforce to notify their long-COVID condition so you can have it in consideration in your return-to-operation process. Monitor the workplace – Inform your people on the required preventive measures to adopt in the work environment (social distancing, masks, vaccines) and ensure those are followed by regularly checking. You might also want to consider implementing testing procedures at your work premises as well as Occupational Health on-site solutions to address any concerns.  Support your long-COVID employees Providing easy access to quality care and treatment for your long-COVID employees is crucial and a key part of your Duty of Care as an employer. Should there be a simple question on their condition or a need for medical assistance, ensure your employees can have access to qualified medical professionals at any time. Reinforce your mental health & wellbeing agenda Mental health and emotional struggles are the most important stigma of the COVID-19 pandemic. If individuals who suffered from COVID-19 are recovered, they still have higher probabilities to experience emotional health issues. There is even a higher risk of this for people with long-COVID. Make sure your people’s emotional needs are addressed by dedicated experts through an appropriate Employee Assistance Programme. Employees should be provided with a route to confidentially discuss their emotional health issues away from their direct managers and team members. This could be with HR or through independent expert support activated by the company and should be communicated widely and consistently. Counselling support services will help you assist your workforce encountering psychological issues.  For further information contact: Gmenier Mendoza, Marketing Communications Manager, International SOS Philippines M: +63 998 963 3802 E: gmenier.mendoza@internationalsos.com

Advanced froth phase control: the key to higher recovery

​  Considered a mix of science and art, flotation is the most widely used process for extracting vital minerals in the modern mining operation. As the amount and type of froth changes from cell to cell, the best recovery systems must be able to accommodate variable froth conditions, otherwise valuable materials end up being lost to tailings. Newer technologies eliminate the guesswork previously associated with flotation, and the latest advancements allow for adapting to the unique conditions within each cell. This improves control of the froth phase and directly affects the mine’s ability to recover either higher volumes or higher grades. As a leading innovator in froth recovery, FLSmidth has created a Froth Recovery Upgrade package that provides customers with more control, resulting in better overall metallurgical performance. The package includes four critical technologies: A level sensor with a robust design and no moving parts, which accurately senses the depth and level of slurry within the cell. Actuators that receive data from the level sensor and adjust the dart valve position to maintain slurry levels. Radial froth crowders to reduce top-of-froth surface area and facilitate movement to the nearest radial launder. Froth cameras, which measure the froth’s velocity and stability and can also infer the froth grade. Ideally, a flotation operation would utilise all four technologies to achieve optimal recovery; however, the full package can be segmented and installed as individual components, based on customers’ needs. This flexibility, and the real-world customer results, are illustrated by the examples below. Customer 1 – Level Sensor and Actuator A large copper mine in Peru approached FLSmidth to increase recovery in an 8-cell flotation bank. The mine’s existing equipment for monitoring slurry levels and controlling dart valves lacked consistency, which caused large deviations in level control. The lack of control and stability reduced overall copper recovery and had a significant impact to the bottom line. Left: Multisense Level Sesnor. Right: Festo Actuator160 Every large fluctuation in level control resulted in two scenarios: First, the cell level would become too high, and pulp would overflow into the launders, resulting in unacceptable grade. Then the level would drop too low and result in little to no recovery of the froth phase, impacting overall recovery. Data from the condition monitoring system revealed an opportunity for improvement, as shown in Figure 1. Sporadic movement of the actuator (blue) caused unstable deviations to the slurry level (green), causing it to fall short of the target level (yellow) needed for optimal performance. Actuator Figure 1 FLSmidth engineers recommended installation of new level sensors and FESTO actuators. The customer agreed to replace its current equipment, and the upgrade yielded immediate improvements. Following the retrofit, slurry levels showed significantly higher stability and remained consistent within the target level, shown in Figure 2. Actuator Figure 2 After a month with the new equipment, slurry levels consistently remained on target. As a result, the customer recovered 0.5% to 0.8% more copper than previously possible with the older equipment. Based on the short-term results, the customer anticipated replacing the remaining flotation cells in the entire plant with new level control. The mine’s return on investment was less than three months. Customer 2 – Adjustable Radial Froth Crowders Another copper mine in Peru consulted with the FLSmidth Flotation team to improve its froth phase control and improve performance of its rougher flotation circuit. The customer was seeking a low-capital solution using its existing equipment and opted to install FLSmidth’s Adjustable Radial Froth Crowders. Radial Froth Crowders Installation of the crowders required no cutting or welding and was completed during a scheduled downtime. With no required permanent structural changes to the cell, modifications could easily be reversed if the customer chose. After installation of the package on just one row of its rougher flotation cells, the customer noticed significant improvements to its operation. Operators were able to decrease reagent consumption, increase the froth phase depth by 3 to 10 cm, and ultimately improve the downstream operations by stabilising concentrate mass flows. With the economic gains seen from the retrofit’s improved performance, the mine retrofitted the remaining two concentrator plants with the same type of adjustable radial froth crowders. Customer 3 – Froth Camera A mine in western Canada contacted FLSmidth with concerns about frequent variations in its copper grade, along with low recovery numbers in its flotation circuit. FLSmidth determined that the frequent variations were caused by poor setpoint control and selection, and that a software solution would provide immediate benefits without a large capital investment.  The three-part solution utilised a combination of Model Predictive Control (MPC), fuzzy logic and FLSmidth’s newest technology in froth vision systems, to improve recovery by 4% at the desired grade with less variation. The first step was to ensure stabile level control throughout the flotation circuit. This was accomplished by controlling the dart valve positions directly using an MPC controller which greatly reduces setpoint error and variation. This process ensures that when a level setpoint is sent to a cell, that the dart valve position will be adjusted to reach the desired level set point in a quick and efficient manner.

Using dewatering systems to improve site efficiency

Photo: Multiflo® mega barges on site in Brazil Dewatering is critical to a mine’s operations and more resources are being allocated to its optimisation. Traditionally, there’s been a tendency among some mine and quarry operations to view dewatering as something to be avoided at all costs – until it can’t be. Therefore, cost minimisation has been the primary focus when it comes to implementing a dewatering or fluid management solution. However, with dewatering becoming increasingly necessary, operators are approaching these challenges in more sophisticated and methodical ways. The trends informing dewatering practices mirror many of those that are observable across all mining processes: a focus on sustainability and the efficient use of energy and other resources; customised, holistic solutions based on each sites unique geological and climatic conditions; and the emergence of new technologies, with a particular focus on real-time monitoring. Dewatering solutions that are carefully designed and implemented have the potential to reduce energy usage, CO2 emissions and significantly lower OPEX over the life of the mine. The overall efficiency is affected by individual elements, but also by how these elements interact and operate with one another. The renewed focus on pumping efficiency requires a significant shift in how many operators have previously approached dewatering and fluid management on site. Because most dewatering programs have been designed with the singular focus of lowering groundwater levels as quickly as possible, they often have excess pumping capacity and oversized pipes and pumps operating at only a fraction of their capacity – a process that’s inherently inefficient. This needs to change to accommodate the increased focus on efficient use of energy and water, which is critical to maintaining a social licence to operate. Multiflo® MF pump unit on site in Indonesia Improving pump efficiency begins with effective monitoring. There have been enormous improvements in electronic control and communication systems in the last few decades. Real time reporting and control of pumping systems can now be an economic reality for almost any mine site. The more visibility you have over your fluid management on site – flow rates, operating pressures, groundwater level, water quality, system relocations, alternate drive solutions, equipment selections to reduce maintenance and repair cycles, etc. – the better placed you will be to install the most appropriate equipment. The industry is moving towards customised solutions and there’s a growing awareness that no two sites are the same, which means a one-size-fits-all approach to dewatering is neither cost effective nor sustainable. Weir Minerals has a global team of dewatering experts who partner with mine operators to assess their specific requirements and provide integrated solutions. With a long and proud history of innovative engineering, Weir Minerals has a team of process and design engineers armed with the latest technology, specific process knowledge and site experience to optimise your dewatering management processes. We take advantage of our global capabilities and engineering skills to provide our customers with the best solution as quickly as possible. With an extensive global network and the ability to service on-site or at one of our 130 dedicated service centres, we are always there when you need us - no matter how remote your operation is.

“After Work Stress Relievers”

CAGDIANAO, Dinagat Islands -- Stress is a word that many people are not a friend of. In fact, never-ending problems or worries arise because of constant stress, dubbing it as the number one enemy of our existence. In the world of the Blue Zone, we can find that most centenarians enjoy their prime years avoiding stress. Their healthy lifestyles take care of their physique and mental stability. In our work environment, stress disrupts people from doing their best. The long tiring jobs drain them physically and mentally. Some may get involved to join drinking buddies to relieve stress -- only to find out that their health suffers as a consequence. Some may even spend more overtime to get their jobs done, only worsening their physical conditions as they already are overworking. It is unproductive and unsafe. Continuous stressful work for longer periods will cause fatigue, resulting in eye strain, back pains, and other maladies. Many companies have created many ways to get their workers to embrace a healthy lifestyle, and Cagdianao Mining Corporation (CMC) is one of them. At the heart of the campsite lies a large room stuffed with weights and training equipment, the humble FITNESS GYM. CMC Fitness Gym’s history goes back a decade ago. It was a suggestion from a local Fire Brigade to build an indoor venue for the CMC workers to exercise for health reasons and at the same time, to boost up their morale. There was no fitness equipment at that time yet, so some workers improvised a bench press made from used campsite lumber, and dumbbells and the barbell weights were made from junk humungous dump truck metal gears. Currently, some employees go out from the campsite and hit the road for a bicycle ride, a hike, or even jogging a few kilometers and back. Some may play at a half-courted basketball ground. In the past, the company had a program called “Shape-up CMC,” which introduced the exercise regimens like Zumba (which gradually dissolved), but nothing can beat the camaraderie inside the Fitness Gym (still going active and improving). Inside the gym, you can already sweat out what you can do running by using the thread mill. The thread mill can be digitally programmed according to your needs like setting up how many minutes you want to run or walk. You can also program a steeper incline to increase difficulty and challenge yourself more. You can try other training equipment for the muscle that you preferred to get toned. Exercising outside the camp premises could mean a higher possibility of injury (e.g. dog bites, sweltering heat of the sun, dust, sprains, knee tendonitis, dangerous slippery roads and the like). Inside the gym, you may encounter minor injuries, too, but thanks to the constant presence of the CMC work-out buddies, you are guarded. These work-out buddies are employees from different departments who love to sweat their stresses out. It may sound strange, but the more they sweat, the more that they are having fun. In the scientific world, this is called… feeling good brain chemicals -- endorphins, dopamine, norepinephrine, and serotonin are released to create a cocktail of enjoyable sensational experiences.   Although the repetitive physical movements and weight resistance is tiring, the mood is converted into something positive through a healthy transformation of body cells, muscles, and brain tissues.   After the workout, you will feel exhausted but that exhaustion will give you a better sleeping cycle. Once you have a good night's sleep, in the morning the feeling of soreness prevails but it’s a signal that your body is transforming into a better and healthier one. “When I started in the field of fitness, I thought I needed to be healthy and physically strong under the influence of a best friend, I saw in him the dedication and motivation that pushed me to start going to the fitness gym and work out. And there I proved to myself that my decision was right from the advice of my close friend to enter the field of fitness, it also led to my diet discipline to eat healthy and nutritious foods that help me become strong, have a healthy body and mind. Time and health are two precious assets that we don't recognize and appreciate until they have been depleted.” – Junelan P. Petilo (CMC ERT Coordinator / Safety Inspector) Hitting the fitness gym can also help build new friends inside the company that works at other departments. The CMC work-out buddies are also encouraging other co-employees to join them especially those that are too dependent on Medical Care benefits and living a sedentary lifestyle. You cannot be healthy by just wishing about it: you have to take action; do it and live by it.   Most of the CMC work-out buddies’ interests and conversations are focused on the well-being of every individual. You can enjoy physical stimulation through working out while having social stimulation as well.   “Am happy that I belong to a company that consider its employees’ health as a fundamental key to achieving goals, believing that a person’s well-being is second to none in terms of productivity. In-house fitness facility is convenient and time saving, of course, the camaraderie and friendship is priceless. Taking care of one’s self is a no brainer as Jim Rohn famously quoted ‘Take care of your body, it’s the only place you have to live’.” – Mcdodd Baylon (CMC Ship Loading Supervisor) CMC also improved its employees’ health and wellness by catering them a healthy meal from nutritious recipes provided by their very own Dr. Alvin Pura (CMC Company Head Physician).     This healthy lifestyle is crucial to the success of the company, as Papa Bear (John-Eric S. Taburada) always says: “I don’t want to be a liability to the company, and a great start would be, engaging in constructive habits -- starting with my HEALTH.”

Imelda Residents: Help Came When We Needed It Most

A helping hand. TVIRD’s Community Relations team led by Khalil Tabernero distributed food packs to Imelda Town’s flood victims who were lining-up alongside the company’s service vehicle.  Physical distancing was strictly implemented in the queues while some food packs were delivered directly to households by the team. “It was a touching gesture.  The assistance provided to us came when we needed it most.  Thank you so much, TVIRD,” said Imelda Town residents who were provided with food packs by TVI Resource Development Philippines Inc. (TVIRD). The assistance came after the devastating storm battered the town and hit Barangay Poblacion the hardest. Danny Gamil, leader of a barangay purok (a subset of a barangay) and neighbor Nolyn G. Palme said the arrival of the food packs helped their families survive for days after Storm Crising brought heavy flooding. Gamil is one of the town’s earliest settlers.  He said all the residents of his purok and others of this barangay received the food packs delivered by the company’s Community Relations personnel who were led by Khalil Pope Tabernero. The company’s efforts provided immediate relief to an estimated 400 families in the municipality. Earlier, TVIRD provided assistance to some 250 families from Barangays Dimalinao, Kahayagan and Dipili directly after Crising battered these barangays with strong floods and extraordinary rainfall.  PAGASA warned of “isolated to scattered flooding, including flash floods and rain-induced landslides” in vulnerable areas.  Specifically for Zamboanga del Sur, this is not the first time that a natural disaster of this magnitude brought savage destruction to homes and farmlands.  A touching gesture “I was really touched, seeing all those goods delivered to us by TVIRD.  Its arrival comforted us, made us see the goodness of men,” said Palme, 29-year old wife of a fish vendor and mother of three.  She said that their family had no income for days and that she and her husband have been clearing their house of debris after it was submerged by flood water. “Everything was washed away by the flood.  We only salvaged our TV set and a cooking utensil.  We are hard-up and do not have income.  Adding to our misery was the lockdown imposed on us again – we cannot even go out.  But thanks to TVIRD’s food packs, which sustained us for several days,” Palme said. Imelda food packs being distributeded Farmer and tricycle driver Gerson F. Bacleta, said TVIRD’s help was unexpected, especially since Imelda is located almost 50 kilometers from TVIRD’s facilities in Bayog Municipality, Zamboanga del Sur Province.   “We did not expect it, but I am grateful because the assistance helped feed my family for three days.  It was the only assistance that we received after the storm,” he said.  “Sadly, my rice land is buried with mud and can no longer be salvaged,” Bacleta shared.  He would have harvested about a month after the storm. Devastating flood Gamil said the May 14 flood was “devastating.”  However, he also refuted reports that it was the first time Imelda town experienced this kind of flooding. “Hesus, 47 anyos na ko. Dili lang kay kini ang baha nga nakahatag ug daku nga kadaut sa among lungsod. May mga baha kaniadto nga nalunopan pod ang mga balay (Jesus!  I am 47 years old already.  This is not the only flood that brought so much destruction to our town. There were floods before that also submerged houses here),” he said. Imelda is a fourth-class municipality situated along Sibugay River, which is considered the longest body of water in Sibugay Province.  During the May 14 flooding, a huge volume of water from the river found its way to Imelda and other towns of the province.
