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.

New Report Identifies Major Carbon Reduction Opportunities in Global Mining
New analysis lays out the scale of the mining industry’s energy use and identifies ways it can be reduced using currently available technologies Materials such as copper, lithium and nickel play an essential role in the technologies like electric vehicles and renewables that will help the world meet its decarbonisation targets As demand for these metals increases, the mining industry must itself become more efficient and environmentally sustainable The global mining industry must move away from legacy systems and processes if it is to meet the challenge of decarbonisation, according to a new report released today which calculates mining’s share of global energy consumption and identifies ways the industry can aid the transition to net zero emissions needed to limit temperatures in line with the Paris Agreement. The report, commissioned by the Weir Group plc, analyses mine energy data from over 40 published studies to give a comprehensive understanding of where energy is consumed in mining and minerals processing. It shows that the total amount of power used by the mining industry – which plays an essential role providing the metals used at the heart of the modern economy – is equal to c.3.5% of global energy use. The metals produced by mining are critical for enabling the global transition to low-carbon infrastructure. But without action, energy use in mining itself is set to trend higher in the coming years as demand increases for metals like copper, nickel and zinc. The report suggests there are technologies available today that could make a significant difference to this trend. For example, it highlights that comminution – i.e. crushing and grinding processes – is the single biggest user of energy at mine sites, typically accounting for 25% of mining’s final energy consumption. This is equivalent to the power used by 221 million typical UK homes, or c.1% of total consumption globally. Comminution is therefore a natural target for the most impactful energy savings opportunities. Small improvements in comminution technologies can lead to relatively large savings in both energy consumption and greenhouse gas emissions. For example, a 5% incremental improvement in energy efficiency across comminution could result in greenhouse gas emissions reductions of more than 30m tonnes of CO2-e. The replacement of traditional comminution equipment with new grinding technology also reduces indirect emissions in the mining value chain, for example by removing the need for the manufacture of emission-intensive steel grinding balls. Of the remaining energy consumption by the mining industry, diesel in varied forms of mobile equipment accounts for 46%, electricity in mining (ventilation) 15% and “other electricity” 14%. Other significant opportunities identified by the report for reducing mining’s energy consumption include optimisation, big data and artificial intelligence. In addition, if zero emissions energy sources are deployed for mining equipment – e.g., renewable energy, energy storage and alternative fuels – then the industry may well be able to achieve zero emissions, leaving a relatively small role for offsets and carbon credits to play. The report comes as the mining industry is under ever-greater pressure to produce essential minerals that support some of the biggest global structural trends, from population growth to urbanisation and decarbonisation. Copper, nickel, steel and lithium are core components of electricity transmission and storage, electric vehicles and renewable energy infrastructure. The move to a decarbonised economy will result in increased primary consumption of these mined commodities, even after factoring for recycling, so it is important that mining itself becomes more sustainable. Download the independent Mining Energy Consumption 2021 report here: www.energysavingsinmining.com Commenting, Weir Group Chief Executive Jon Stanton said: “The mining industry is central to economic development globally, with critical minerals enabling the low-carbon transition required in the rest of the economy. But the environment in which it will operate in future will be very different from the past, requiring comprehensive change and investment. In short: mining needs to become more sustainable and efficient if it is to provide essential resources the world needs for decarbonisation while reducing its own environmental impact.This report is an important contribution to that debate which we hope will spark thoughtful conversations around the world on the way forward.” Alison Keogh, Chief Executive of the Coalition for Energy Efficient Comminution, said: “This report highlights both a challenge and an opportunity to revitalize cross-industry discussion and actions on decarbonisation and ESG solutions. We invite industry leaders to actively contribute and collaborate through mining-vendor-research partnerships and share knowledge. Together, we can accelerate improved energy, emissions and water footprint across industry faster.” Ricardo Garib, Weir Minerals Divisional President commented: “Weir Minerals is focused on making mining more efficient and sustainable by leading technology change in the industry. Our Enduron HPGRs are increasingly replacing conventional milling systems in comminution (crushing, screening and grinding) circuits because of their substantially lower energy consumption, finer rock reduction requiring less water downstream and potential for significant total cost of ownership reductions.” Stuart Hayton, Managing Director of Weir Minerals Netherlands, where the Enduron® HPGRs are designed and manufactured, added: “Not only do Enduron HPGRs require as much as 40% less energy than traditional alternatives, their wearable components last much longer and the maintenance time required to replace worn out parts is significantly lower. The estimated carbon saving of each Enduron HPGR in operation is equivalent to taking more than 3,600 petrol fuelled cars off the roads each year.” Notes: The report quantifies energy use in five commodities: copper, gold, iron ore, nickel and lithium. Bringing together mine energy use data from more than 40 published studies (each of which references dozens more studies) from 2007 to 2020 into a single narrative, the report aims to build a more comprehensive understanding of energy use in the mining industry. Using the current production rates of the commodities in question, and the energy intensities for each of the commodities, a total of 1,68 EJ/a (1,680,000,000,000,000,000 joules per year) has been calculated. This is approximately 0.5% of total final energy consumption globally. Published information indicates that the entire mining industry consumes approximately 12 EJ per year – or 3.5% of total final energy consumption globally. Assuming that present trends continue, there will be 250m electric vehicles on the road by 2030. To meet this demand, production of cobalt, lithium, graphite and nickel will need to be scaled up significantly. Current projections show that the current rate of decarbonisation globally is far below what is required to meet the goals of the Paris Agreement. A sustained decarbonisation rate of up to 7% per year, year on year should be sufficient to achieve the goal of a temperature increase of well below 2°C by 2100. For the mining industry, there are multiple ways to achieve decarbonisation including energy efficiency and fuel/energy switching. Many of these opportunities are starting to be explored by both the mining companies and the mining services providers, who see decarbonisation and energy reduction as a key way to reduce exposure to the risks of climate change.

FNI posts higher nine-month net income of P2.13 billion
Photo credit: Global Ferronickel Holdings Global Ferronickel Holdings, Inc. (FNI), a diversified Filipino company with interests in ferronickel ore mining and processing, logistics and port operations, and cement and steel production, recorded a net income of P2.13 billion in the nine-month period that ended September compared to the P1.86 billion it posted during the same period last year. The results are driven by the Group’s flagship mining project in Surigao del Norte operated by Platinum Group Metals Corporation (PGMC). FNI's revenues on the sale of medium-grade nickel increased on the back of favorable forex rates and higher average realized price, while shipment volumes reel from inclement weather and a lower price for low-grade ore. The sale of nickel ore for the nine-month ended September 30, 2022 slides to 3.150 million wet metric tons (WMT), lower by 1.078 million WMT or 25.5%, compared to 4.228 million WMT of nickel ore in the same period last year. The Group only completed 58 nickel ore shipments against 78 shipments during the same period last year due to erratic weather conditions registering 161 rainy days to 137 last year. The resulting sales mix was 78% low-grade ore and 22% medium-grade ore in 2022 versus the previous period’s blend of 81% low-grade ore and 19% medium-grade ore. Shipments consisted of 2.450 million WMT low-grade nickel ore and 0.700 million WMT medium-grade nickel ore compared to 3.424 million WMT low-grade nickel ore and 0.804 WMT medium-grade nickel ore in the same period in 2021. The average realized nickel ore price for the period ended September 30, 2022 is USD28.89/WMT lower by USD1.89/WMT or 6.1% compared to last year’s USD30.78/WMT. Low-grade ore is USD25.49/WMT lower by USD4.30/WMT or 14.4% against last year’s USD29.79/WMT. On the other hand, medium-grade ore stands at USD40.79/WMT higher by USD5.80/WMT or 16.6% versus last year’s USD34.99/WMT. The average realized Peso over USD exchange rate for the Group’s export revenues is P54.87 compared to P49.22 in the same period last year, higher by P5.65 or 11.5%. “Overall outlook for FNI looks reassuring. With the opening of our Palawan mineral project, we expect healthier returns for our stakeholders. Although weather conditions have not been permissive, we have continued to improve our operations and pursue our expansion plans,” said FNI President Dante R. Bravo. FNI recently disclosed its 20% stake in China's Guangdong Century Tsingshan Nickel Industry Co. Ltd (GCTN) to enhance synergies between FNI with its nickel ore mines and GCTN as an ore processor and provide a steady value-adding enterprise for the Group. As a testament to its growth and core policy to strengthen systems and processes, PGMC has received ISO certifications for its Quality Management System (ISO 9001:2015), Occupational Health and Safety Management System (ISO 45001:2018), and Environmental Management System (ISO 14001:2015) as an Integrated Management System (IMS). The certification applies to all activities in the mining operations of nickeliferous laterite ore and other associated minerals from planning to ore production, hauling, loading and port operations.

DMCI Mining nets P1.2 billion in 9M
Photo Credit: dmcihouse.net DMCI Mining Corporation saw its net income decline by 17 percent from P1.41 billion to P1.17 billion during the first nine months of the year owing to lower nickel ore shipments and average nickel grade sold. “We expected a severe profit decline because of the depletion of our Berong mine late last year. Fortunately, the bullish nickel market allowed us to ship even the low-grade inventory of Berong,” said DMCI Mining president Tulsi Das C. Reyes. “Strong nickel prices and local currency weakness also moderated the impact of lower shipments on our bottom line,” he added. For the third quarter alone, net income tumbled by 56 percent from P181 million to P80 million due to the combined effect of lower shipment (-50%), flattish nickel grade sold (-1%), higher selling prices (+31%) and favorable average foreign exchange rates (+10%). Total shipments declined at a slower pace from January to September as the Berong mine did better than expected in the first half. Consequently, nickel ore shipments only fell by 25 percent from 1.45 million wet metric tons (WMT) to 1.09 million WMT. Despite a 4-percent decrease in average nickel grade sold from 1.38% to 1.33%, DMCI Mining posted a 16- percent improvement in nine-month average selling price from US$43 to US$50. Magnifying the impact of higher selling prices was a 10-percent increase in foreign exchange rates from US$ 1:Php 49 to US$ 1:Php 53. At the end of September, total inventory plummeted by 76 percent from 450,000 WMT to 109,000 WMT, mostly (81%) coming from Zambales. Article courtesy of the Philippine Stock Exchange

E-vehicle boom opens new opportunities for PH mining
Developing the electric vehicle (EV) industry is opening new opportunities for the Philippine mining sector, a company executive said Wednesday. In a media roundtable, DMCI Mining president Tulsi Das Reyes said the e-vehicle sector has provided new opportunities for the mining industry and his company is keen to take part in this development. He described that mining became a "sunset business" before the growth of the e-vehicle industry. "Prior to the EV boom, stainless steel was going nuts, and they don't have capacity already for the stainless steel market. And China is the only growth for stainless steel, all other countries in the world (are) slowing down," Reyes said. He said the growing demand for e-vehicles globally has offered a "fresh light" for the mining business. Nickel is a component for e-vehicle batteries. "Without EVs (e-vehicles), we would (have) ended so many other niche market(s). So it was a huge impact," Reyes added. In the recent foreign business missions of the Department of Trade and Industry (DTI) in the United States, South Korea and Japan, companies from these countries expressed their interest in the Philippine e-vehicle industry, including manufacturing batteries for electric cars. Part of the DTI's Make It Happen in the Philippines campaign is to attract investments for integrated mineral processing to have value-added activities in the mining industry instead of exporting minerals as raw materials. Reyes said DMCI Mining is in talks with possible foreign partners to explore opportunities for integrated mineral processing here, including Indonesian and Chinese partners, but this will require adequate infrastructure in place and support from the government. Meanwhile, DMCI Mining net income in January to September this year declined by 17 percent to PHP1.17 billion from PHP1.41 billion in the same period last year. The lower profit for the first nine months of 2022 was mainly due to decline in shipment. "Strong nickel prices and local currency weakness also moderated the impact of lower shipments on our bottom line," Reyes said. Article courtesy of the Philippine News Agency
