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.

PNG Vanilla Company Partners Expo2020 Team
Dr. Nancy Irwin (left) with the Deputy Commissioner General for Expo2020 and Head of the PNG Expo2020 Secretariat, Mrs. Jacinta Warakai-Manua began the partnership to tell the PNG Vanilla story in Dubai, by exchanging ideas in Port Moresby last week. A vanilla production and export company is partnering with the PNG Expo2020 Team to promote their products in the Dubai World Exposition that starts in October this year. KAMAPIM, a company working with landowners in the Madang and Morobe Provinces produces top quality vanilla beans and is already exporting to the EU market. The Managing Director of the company Dr. Nancy Irwin, met with the PNG Commissioner General to Expo2020 Ambassador Joshua Kalinoe and his Deputy Mrs. Jacinta Warakai-Manua in Port Moresby last week to firm up the arrangements. Dr. Irwin said Kamapim (pidgin for develop and to improve) concentrates its efforts in producing the best quality bean for the international market through quality assurance production methods. “PNG farmers can grow anything, they have instinctive ability to grow well any crops. When I first started the project, the quality of the beans were poor, full of fungus due to lack of processing knowledge. We saw huge potential of the organically grown beans and started working with landowners through a cooperative production and marketing structure to improve quality” “The company provide extension services to farmers and buy the beans directly, ensuring farmers are paid a fair price for their efforts”, she said. Dr Irwin said the beans are tested internationally and are consistently classed as the top-quality A grade level. “While PNG has a good perception of growing environment friendly organic vanilla beans, the challenge is for the relevant Government authorities to work with farmers to improve quality. I believe the cooperative production methods applied by our company, Kamapim, could be used nationally as one of the models to improve quality for the export market as well as to maximize revenue gain for farmers”, Dr. Irwin said. She said the company is looking forward to partnering with the PNG Expo2020 Team to tell the PNG story and to connect with niche importers in Dubai and the Arab world in general. Dr. Irwin said the company would promote its products in specially branded PNG Expo2020 containers to create visibility for the country as well as to preserve quality at the company’s cost.

BPNG Goes For Review
Treasurer Ian Ling-Stuckey has revealed the terms of reference for a review of the Bank of PNG, as well as the members of the review panel. Former Chief Secretary Robert Igara will lead the study, which was planned in the Supplementary Budget for 2020. Former central bank governor Sir Wilson Kamit and Australian professor Dr Stephen Howes are the two members. “These very eminent people, all of whom have detailed experience of the PNG financial system and reform, will be working to a term of reference approved recently by the NEC,” Ling-Stuckey said. “It is the first review of the central bank and the Central Banking Act 2002 since Sir Mekere Morauta’s financial system reforms when he was prime minister from 1999 to 2002. “Much has changed since then, and the effects of the coronavirus pandemic, along with substantial technological advances, have made the need for a review even more urgent. “The aim is to modernise the bank and the legislation in line with international developments, and make it more responsive to prevailing circumstances while preserving its independence.” The study is scheduled to be finished in time for Parliament's November session. “An independent advisory group was also established by the late Sir Mekere when looking at the changes that led to the Central Banking Act 2000,” he said. “Igara, currently the University of Papua New Guinea chancellor, was chief secretary at the time, and Sir Wilson was the governor of the Central Bank. “Prof Howes, head of the Development Policy Centre at the Australian National University, has long been involved in PNG research and advice and consultation, particularly in relation to national development.” Reference: The National (8 June 2021). “BPNG going for review”.
