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.

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 Tourism Promotions Authority (TPA) and Bougainville TPA signs MOU
The Department of Commerce, Trade and Industry reached another milestone recently when it signed a Memorandum of Understanding (MoU) with the Papua New Guinea (PNG) Tourism and Promotions Authority (TPA). The MOU paves the way forward for both parties to continue bilateral partnership based on the understanding of tourism and promotions in Bougainville. The MOU was signed by the PNG TPA and the ABG Department of Commerce, Trade and Industry on the understanding relating to a joint partnership for the protection and preservation of tangible and intangible culture, development and promotion of tourism, contemporary culture and the arts and sustainable tourism in the autonomous region of Bougainville. ABG Vice President and Minister for Commerce Trade and Industry, Hon. Patrick Nisira (MHR) acknowledged the PNGTPA for its tremendous support so far since the first MoU was signed in 2016. The support has cemented many agreements already signed and has proven that Bougainville is truly a tourism destination that is worth investing time and money on. Mr. Nisira acknowledged the PNG TPA officers for their continuous negotiation with the Bougainville partners in pushing for significant income generating programmes to proceed in the region. “Standing here today it gives me great pleasure to witness and participate in this significant event that will go down in history books of this nation to be. We are here today to mark this important event on the signing of the MOU between my ministry and the department of national government and PNG Tourism Promotions Authority (PNG TPA).” This agreement adds value to our collective vision, ideas and consultations that the local tourism and cultural practitioners in both government and private sectors, he said. “As a way forward the agreement presents a realistic and workable approach to tourism development and its sustainability in the region.” “The MOU also sets out a framework for future development for tourism emphasizing on effective and determined and holistic approaches.” He said that the agreement generally outlines the pros and cons of tourism development in Bougainville and the framework and strategy of reaching the targeted goals and vision earmarked to reaching the overarching goals of economic building and development. Deputy Chief Secretary for Operations Anthony Koiri approved and signed the MOU on behalf of the Bougainville Public Service Chief Secretary who is on sick leave at the moment. The signing was witnessed by the staff of the PNG Tourism Promotions Authority (PNGTPA), Department of Commerce, Trade and Industry, senior officers and a small crowd at the Bel Isi park.

PNGEITI POSITION ON PORGERA MINE LEGACY TAX ISSUES
The PNGEITI Head of Secretariat Mr. Lucas Alkan says all parties to the Pogera Mine must adhere to rules governing the extractive industry, particularly when dealing with fiscal matters that must be administered and observed according to law. His comments follow a news article on The National citing the Internal Revenue Commission (IRC) that unmet tax obligations of the Pogera mine stood in the way to expedite the mine re-opening process. Mr. Alkan says a workable and timely strategy that does not impinge on basic laws is a way forward. Below is the full comment on this issue. “The Papua New Guinea Extractive Industries Transparency Initiative (PNGEITI) commends The National newspaper for attempting to bring to light what appears to be the final outstanding issue (among others) in the Porgera Mine recommencement negotiations (more on this in footnote). We’ve noted from the reporting that taxation matters are legacy issues that appear to be standing in the way for the multi-million-kina Porgera Gold Mine to re-open. We have observed that the Government was on track to conclude negotiations and re-open the Mine by June last year, however this did not eventuate as anticipated. Attempts to reopening the Mine in the second half of last year was not feasible due to the national general elections and the formation of government. It appeared that all negotiations were concluded and a new Porgera Mining Agreement Framework was in place for the Mine to be re-opened in the first quarter of this year. Surprisingly, we learn that an old Porgera Tax liability dispute is standing in the way for the Mine to be re-opened. The early recommencement of the Mine, preferably within the first quarter of this year is critical for the country as the lead time required for mobilizing resources and the significant start-up capital needed to get the mine back into its full operating capacity would be a significant challenge. On this, we are aware there are also discussions going on with the developer and the government as to who is going to meet the startup cost but we understand Barrick Niugini Limited might meet the full cost of starting up the Mine and government would refund later but unsure as to whether this understanding has been reached or not yet. With regards to the current standoff, the EITI based on its global best practice principles is of the view that the existing law governing taxation matters must dictate or take precedence over any political intervention. We do not know the specifics of the on-going tax matter but understand that it is related to a tax dispute concerning the ‘old Porgera Mine’. If it is a significant amount of tax owed by Barrick to the Government based IRC’s audit in 2013 then it is a legal tax obligation that Barrick and its joint venture partners need to settle as required by law. We fail to understand as to why the old Porgera tax obligation/liability clause was inserted into the new Porgera Mining Framework Agreement making it a condition to resolve this legacy tax issue before reopening the Mine. If whatever was reported and commented by PM Marape recently is true then Barrick Niugini Limited and the State need to speed up the negotiation process and resolve this dispute immediately. Both parties should exercise good faith – Barrick Niugini Limited should not pull strings on this old Porgera tax liability matter and delay the re-opening of the Mine. It is understood the State (IRC) may not easily forego if there is a substantial amount of tax liability to be paid by the operator. Whatever the parties decide to do, they should resolve the tax liability issue through the due process of law but allow the Mine to re-open immediately under the New Porgera Framework Agreement. Political intervention is not recommended to resolve this dispute as this can undermine investor confidence, set bad precedence for the Government and create an uneven playing field for project developers. Barrack Niugini Limited should not put undue pressure on the State to resolve this matter politically in order to re-open the mine as it is not a best business practice. All stakeholders and the citizens have the right to know the specific issues or the nature of this tax liability issue between Barrick Niugini Limited (BNL) and the Internal Revenue Commission (IRC) as the continued delay in re-opening the Mine continues to have negative consequences on the economy. The prolonged delay has not only resulted in significant revenue loss to the Government (including the provincial and local level governments in the impacted resource area) but also loss of employment, business opportunities and spin-off benefits to the landowners and the wider communities. The shutting down of the Mine 3 years ago has had significant negative consequences on the economy including the current foreign exchange shortage that has constrained business operations in the other sectors of the economy. Porgera Mine had been a good source of foreign exchange inflows and its continued shutdown will definitely not going to contribute to the 4% economic growth (that was largely to be driven by the extractive sector) projected for by the World Bank for last year and the real GDP growth of 4% projected for this year in the 2023 National Budget. PNGEITI commends the transparent negotiation process to date that took substantial amount of time and effort to ensure the interests of all parties were reflected in those agreements. We encourage all parties to continue to respect and observe the laws of the land in this dispute resolution process to address the tax liability issue. We believe that a win-win situation for both parties (Government and Barrick) is to re-open the mine first and work together to resolve the outstanding tax liability dispute later going forward.
