New Report Identifies Major Carbon Reduction Opportunities in Global Mining
by PNG Business News - May 11, 2021
- 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.

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.”
- 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.

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.

PM Marape supports development of oil palm industry on a massive scale in PNG
Photo: PM Marape and Governor Bird in discussions with representatives of Pacific Elite Palm Oil Group in Singapore on Monday (November 21, 2022). Prime Minister Hon. James Marape has given his support to development of the oil palm industry in Papua New Guinea on a massive scale. PM Marape gave his support after he and East Sepik Governor, Hon. Allan Bird, met with representatives of Pacific Elite Palm Oil Group in Singapore on Monday (November 21, 2022). The company currently runs an oil palm project in East Sepik, which it wants to emulate in all provinces, saying that it will be an economic gamechanger for the whole country. The company aims to create the largest agriculture-based wealth in the South Pacific, as well as generate electricity for PNG, using oil palm. Governor Bird told PM Marape that if a long-term oil palm development plan was drawn up, with the aim of economic independence for PNG, one million hectares of oil palm grown all over PNG would bring in an extra K100 billion for the country. “We can double our GDP just from palm oil,” he said. “If we go into downstream processing, this K100 billion could double, so that we could be earning K200 billion on top of our current GDP. “The other flow-on to the economy is power production that fits into the grid, carbon credits, increased cattle production, as well as jobs. “Palm oil is amazing because you can do so much with it, including green energy, which can be generated from the waste of palm oil. “If we have 33 operations throughout PNG, similar to what we are doing in East Sepik, 100,000 jobs would be created “This is brilliant.” Governor Bird told PM Marape that oil palm, when made into biofuel, would save the country millions of kina. “If we produce enough palm oil, we don’t need to go out and buy fuel, as we can produce our own,” he said. “It can also bring inflation down as we are no longer importing inflation. “I’m excited because it provides us an escape plan from all these things that are affecting us.” PM Marape welcomed the proposal by Pacific Elite Palm Oil Group and the ideas of Governor Bird, who has helped to grown the vanilla and cocoa industries in East Sepik, and PNG. “As regards expanding nationwide, I invite you to come to Port Moresby, and I will run the investment figures past the super funds and Kumul Consolidated Holdings,” he told the company’s spokesperson Alexander Tho. “A family of investors can easily mobilise the money required for the project. “I also want you to have a stake in the business, and run it, as we cannot do it on our own, in like what Barrick is doing at Porgera Mine.”
