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.

Sampulna cites need for more mineral processing plants to boost PH production
Photo credit: DENR - Mr. Jim O. Sampulna Former Department of Environment and Natural Resources (DENR) Acting Secretary Jim O. Sampulna pushed for the establishment of more mineral processing plants and utilization of rare earth deposits to help increase the country’s mineral production and revenue generation. “Mineral processing plants make the mined mineral ready to use for application. For example, limestone, if processed, will become cement, which is ready to use for construction,” Sampulna cited. “If we have more of these plants and more minerals will be processed in the country, then its value will increase even more than 100 percent, and lesser raw materials will be shipped out to other countries, like Japan or China,” he said. The DENR-Mines and Geosciences Bureau has so far issued 108 mineral processing permits, most of which are for construction materials. Likewise, Sampulna proposed the identification of rare earth elements (REEs), such as scandium and yttrium, in operating mines. Sampulna, who was the former DENR undersecretary for mining, said that these metals are essential parts for many high-technology devices. “The Philippines is conducive to these minerals. It could contribute to the national government through the identification and utilization of these commodities. To date, there are only a few operating mines which have identified REEs,” he said. Sampulna cited that a proposed iron mineral processing plant in Zamboanga had its groundbreaking ceremony on June 18, to support the DENR’s initiatives toward self-utilization of mineral commodities in the country. “We hope that investors will push for the opening of more processing plants in the Philippines,” he said. He also assured Filipinos that the DENR will continue to strengthen its regulation and monitoring of mining operations to ensure sustainable and responsible mineral production in the country.

DENR Awards MGB with Plaque of Appreciation for the Success of the Boracay Island Rehabilitation
Photo: The MGB Boracay Island Rehabilitation Team together with former DENR Secretary Roy A. Cimatu Four years after the Department of Environment and Natural Resources (DENR) spearheaded the rehabilitation of the Boracay Island, the DENR Acting Secretary and Boracay Inter-Agency Task Force (BIATF) Chair Jim O. Sampulna CESO I awarded the Mines and Geosciences Bureau (MGB) a Plaque of Appreciation for its valuable contribution to the success of the Boracay Island Rehabilitation during the BIATF’s culminating event on June 16, 2022. Boracay Island is one of the most developed and densely populated karstic islands in the Philippines. The extensive alteration of its natural landscape, as well as the alleged discharge of wastewater into the sea, posed a major environmental concern, prompting its temporary closure on April 26, 2018. The BIATF then launched the rehabilitation of Boracay island to safeguard its sustainable development. As part of the BIATF, the MGB team, led by Lands Geological Survey Division (LGSD) Chief Liza Socorro J. Manzano, was composed of technical personnel from the LGSD of MGB Central Office and the Geosciences Division of MGB Regional Office No. VI. The team conducted studies on hydrogeology, coastal geohazards, karst subsidence hazard, and geophysical investigations using Ground Penetrating Radar (GPR) and georesistivity. The highly specialized studies sought to provide a holistic understanding of the island’s karstology and the impacts of tourism development to ensure that the rehabilitation efforts of the government are predicated on the ecological sustainability of the small island karst. Ultimately, the results of the GPR investigation on pipes discreetly disposing wastewater and polluting the seawater of Boracay which resulted in the discovery of their existence and eventual dismantling of the same is a "game-changer" relative to the implementation of science-based strategies and crafting of policies for appropriate wastewater and solid waste management in the island.

The Fault with Cobalt: Overcoming the Challenges of Battery Metal Exploration
upply Co., Inc. Cobalt is an important element used to manufacture rechargeable batteries. Cobalt has unique properties that help improve thermal stability, which is critical for the batteries to function properly. It also helps improve some batteries’ energy density, so they can last longer. The demand for cobalt is high, so geologists need fast, accurate tools to help them meet these requirements. Portable X-ray fluorescence (pXRF) analyzers are one of these tools, as they provide on-the-spot material chemistry results. Why Choose Portable XRF for Cobalt Exploration? Portable XRF provides rapid, in situ, multielement geochemistry for immediate results in the field. This is useful for greenfield and brownfield exploration, ore grade and process control, environmental monitoring and remediation, and researching/teaching within the geological/environmental sciences. For battery metal exploration, portable XRF provides decision-quality data faster than traditional, lab-based XRF, and also enables more discriminatory laboratory sampling, helping reduce costs and improve ROI. With sample preparation, pXRF produces high-quality quantitative data that is comparable to laboratory analysis. Challenges with Analyzing Cobalt XRF is prone to inter-element interferences. Iron (Fe) on cobalt (Co) and nickel (Ni) on cobalt (Co) are two common examples. This means that when a lot of iron is present, it becomes difficult for XRF to identify cobalt at low levels. Likewise, the presence of nickel also makes it difficult for XRF to ID cobalt. Unfortunately, cobalt is routinely explored for in the presence of significant amounts of iron and nickel. To solve this challenge, we developed a GeoChem method for Vanta™ pXRF analyzers that offers improved analysis for battery metals exploration by being able to detect cobalt in the presence of iron and nickel. This innovative method overcomes the interference that has historically made it very difficult for portable XRF analyzers to detect cobalt in the presence of these other elements. The method we developed for the Vanta analyzer is built on the current GeoChem method, but with a more sophisticated way of deconvoluting the iron/cobalt/nickel peaks. Before deploying this solution, we tested it on client samples to make sure that it produced good results. Test Results We analyzed 16 samples with high iron content—9% < Fe < 50%, 50 ≤ Co ≤ 6000 ppm, Ni < 500 ppm. We also analyzed 50 samples with a moderate amount of iron—0.5% < Fe < 15%, 16 < Ni < 8000 ppm, 50 ppm < Co < 2.3%. The samples were pulps in XRF cups, and they were analyzed using 60 seconds per beam with no corrections. The graphs below show excellent agreement between the results obtained from a lab and results obtained using a Vanta portable XRF analyzer, indicating that the modified GeoChem method can accurately detect the presence of cobalt when it’s in the presence of both large and moderate amounts of the interfering elements iron and nickel. Geologists now have another important tool that they can rely on when exploring for new sources of this vital element.
