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.

Papua LNG project to Minimise Economic Challenges

Photo: Petroleum Minister Kerenga Kua Petroleum Minister Kerenga Kua has recently stated that the Papua LNG project is critical in addressing some of the economic challenges that are currently faced in the country. He said about K75 billion will be generated over a 15 year period when the project is in progress. He added that the initial stages of the project has commenced with K500 million said to be inputted into PNGs foreign exchange capacity in 2023. During a press conference on Thursday the 9th of March, The Petroleum minister highlighted the progressive stages of the Papua LNG project and emphasized the importance and significance of the benefits that the project will provide. According to studies the project life is expected to operate over a 15 year period that will generate about K75 billion and significantly boost Papua New Guinea's struggling economy. "The K75 billion benefit is inclusive of what comes to the state directly as levies, to Kumul Petroleum, to the landowners as royalties and the provincial governments. All of us put together are going to be collecting and sharing that benefit in the next 15 to 20 years", Kua said.  Minister Kua said that studies for the Papua LNG project began in 2004 following the discovery by Interoil, the resource estimate is in the range of 6 trillion cubic feet of gas and 98 to 100 million barrels of condensive oil.  The benefit of this project is immense and a positive component is the national content which is expected to positively impact GDP, export earnings, forex, revenue to impacted levels of government, landowner benefits and Job opportunities.  Minister Kua said the project developer Total Energies will inject K500 million into the PNG economy in 2023. "The Papua LNG project is a project of national significance for Papua New Guinea and will stimulate business confidence and will provide a significant impetus for our economy", "The Marape-Rosso government places high priority on the delivery of the Papua LNG project, we have an improved deal for our people, and improved contribution for our national contractors and workforce. The government strongly supports the Papua LNG project and encourages all stakeholders including project partners to work diligently to deliver the project on time and on budget", Minister Kua said. Petroleum Secretary David Manau was also present at the conference, he highlighted that the petroleum department will work closely with impacted provincial governments and landowners as this is important in ensuring that all stakeholder grievances are discussed and addressed. In light of this, a development forum is expected in the third quarter of this year. Meanwhile, Kua also revealed a unique aspect of the upcoming project which will mitigate the project's carbon footprint and is set to make PNG in  becoming the first country in the Asia Pacific region and only the second on the world to re-inject carbon dioxide back into the well pad in a LNG project. He said the re-inspection of carbon dioxide into the well pad is a significant step towards reducing the project's carbon footprint and will help mitigate the environmental impact of the project and contribute to Papua New Guinea's efforts to combat climate change. The Papua LNG project is a joint venture between the PNG government, TotalEnergies and Exxon Mobil. It is one of the largest investments in the country's history and is expected to generate significant revenue for PNG's economy. Total Energies holds 40.1 percent interest in Papua LNG, along with its joint venture partners Exxon Mobil (37.1 percent) and Santos(22.8 percent). The Papua New Guinea government may exercise a back-in right of up to 22.5 percent interest at the Final Investment Decision (FDI) planned by end of 2023 to early 2024 and production will be scheduled for four years later.
