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.

Credit: AusAmbPH Twitter Page As the Marcos administration becomes bullish in utilizing a public-private partnership (PPP) model in infrastructure projects, the Australian government will be providing its technical expertise in rolling out infrastructure projects under the PPP. Australian Ambassador to the Philippines Hae Kyong Yu PSM told the Philippine News Agency in an interview at her residence Wednesday that the embassy will be launching the Partnerships for Infrastructure (P4I) on March 24. “Infrastructure is a big area that the Philippines is focusing on, and I know President (Ferdinand R.) Marcos (Jr.) has announced that he wants to utilize PPP more where it’s possible. So we are working closely with the Philippine government to share with them how Australia has done it,” Yu said. P4I is an Australian government initiative that brings together experts from the public and private sectors as well as the academe to help Philippine government agencies involved in infrastructure development in the preparation stage of projects that would be under a PPP model. “We can help them with all the project preparation stage. How you do actual cost-benefit analysis of potential projects, and then how you prepare documents for possible procurement, tender processes, and things like that,” the envoy cited. She said that aside from the PPP Center, the P4I also aims to closely work with other agencies including the Department of Transportation, the Department of Energy, the Department of Finance, and the National Economic and Development Authority (NEDA), among others. Yu added that the Australian government will be closely working with the administration through the P4I in meeting its diverse infrastructure requirements, including roads, transport, energy, and public investment management. The Australian envoy said a number of Australian companies have been involved in infrastructure projects in the country. Early this month, NEDA Secretary Arsenio Balisacan announced that the NEDA Board approved PHP9 trillion worth of flagship infrastructure projects, with 45 of these projects possibly being funded through PPPs. “The government shall harness the financial and technical resources of the private sector, which allows the public sector to allocate its funds for greater investment in human capital development, especially to address the scarring in health and education due to the pandemic, and provided targeted assistance that protects vulnerable sectors from economic shocks,” Balisacan had said.

PBBM boosts transport sector thru big-ticket projects
Photo credit: Department of Transportation Several big-ticket infrastructure projects in the transportation sector have been approved or are already being implemented by the administration of President Ferdinand R. Marcos Jr., the Department of Transportation (DOTr) reported Monday. In a statement, the DOTr said the Cebu Bus Rapid Transit Project, Davao Public Transport Modernization Project, EDSA Greenways, the Light Rail Transit Line 2 (LRT-2) West Extension, and the Light Rail Transit Line 1 (LRT-1) Cavite Extension are all ongoing as of March 9 according to the National Economic and Development Authority (NEDA). These projects are among the 67 infrastructure flagship projects (IFP) that have been greenlit or are already underway out of the 194 high-impact projects under Marcos’ "Build Better More" program. In the rail sector, these approved and ongoing projects include the Metro Manila Subway Phase 1, Mindanao Rail Phase 1, Metro Rail Transit Line 3 (MRT-3) rehabilitation, Metro Rail Transit Line 4 (MRT-4), Metro Rail Transit Line 7 (MRT-7), New Cebu International Container Port, New Manila International Airport (Bulacan International Airport), North-South Commuter Railway (NSCR), Philippine National Railways (PNR) South Long Haul, and the Subic Clark Railway. The New Dumaguete Airport Development Project (Bacong International Airport) and the Integrated Flood Resilience and Adaptation (InFRA) Phase 1 have also both been approved by NEDA, with six projects awaiting approval. Last week, the NEDA Board, led by Marcos, approved 194 high-impact priority projects with a total cost of around PHP9 trillion. The board also approved amendments to the 2013 Joint Venture guidelines to support the government’s push for more investments in the country’s infrastructure. PNR suspension Meanwhile, Senate President Pro Tempore Loren Legarda has expressed alarm over an impending suspension of select PNR routes due to the NSCR, saying it will affect thousands of commuters, mostly students and workers. “The welfare of the riding public should always be prioritized yet it remains to be seen whether such proposed solutions would effectively and sufficiently address the riding public's urgent demands in time for the imminent suspension of the operations of the PNR,“ Legarda said in her explanatory note on Senate Resolution No. 546. The PNR plans to suspend operations of certain routes for up to five years to facilitate the faster construction of the 55-kilometer NSCR. The construction will start in May and PNR may suspend the routes between Governor Pascual in Malabon City and Calamba City in Laguna, and well as Alabang, Muntinlupa City to Calamba. The Tutuban, Manila-Alabang route will be suspended in October and will affect between 20,000 and 25-000 passengers daily. Legarda urged the Committee on Public Order, chaired by Senator Grace Poe, to look into the impending suspension and come up with alternative solutions. Article courtesy of the Philippine News Agency
