Weir Minerals and Andritz have signed an agreement at MINExpo 2021 expanding their shared commitment and strategic cooperation to supply equipment for processing tailings in the mining industry. The foundations of this agreement have been built on a shared understanding and vision to enable the sustainable and efficient delivery of the natural resources essential to create a better future for the world.
Since 2018, Weir Minerals’ and Andritz’s partnership has seen them collaborate on joint tailings projects. This shared history as partners – a collaboration made stronger by the quality of individuals on both teams – has reinforced their abiding belief that together, both Weir Minerals and Andritz are stronger.
This shared success has led both Weir Minerals and Andritz to renew their on-going commitment and announce they’ll be expanding their offer to all regions around the globe.
Utilising Andritz’s proven separation and dewatering technologies, Weir Minerals has strengthened its whole-of-mine capabilities, showcasing market-leading products from extraction to comminution, mill circuit and tailings management.
‘Weir Minerals has been providing tailings solutions for decades; we have dedicated research facilities – the Weir Technical Centre in Melbourne, Australia and the Sustainable Mining Centre in Venlo, Netherlands – that are challenging conventional ways of thinking about tailings, while also developing practical, innovative and sustainable solutions that will reduce operating costs and improve safety,’ Ricardo Garib, Weir Minerals Division President said.
‘Decreasing ore grades mean that mines are producing more tailings than ever before. One of the challenges with tailings management is that there cannot be a one-size-fits-all approach; each mine requires a tailored solution that carefully considers the minerals being processed, as well as the site’s climatic and geological conditions. Weir Minerals prides itself on having both the expertise and equipment that allows us to partner with miners everywhere to plan and implement tailings solutions based on their operations’ unique challenges and this agreement with Andritz enhances those capabilities,’ he said.
‘Andritz has a long history working across a range of different industries. We are very proud of the work we’ve done with Weir Minerals; together, we’re excited about continuing to provide a joint offering of sustainable and value-added tailings solutions. Both companies bring a different expertise and know-how to the partnership; we complement one another and ultimately it’s our customers who’ll benefit,’ Steve Huff, President Andritz Separation said.
Tailings management forms an important element of Weir Minerals’ broader integrated solutions approach, which considers problems and challenges from all perspective and draws on a range of experts – process engineers, design engineers, product experts and materials scientists, among others – to identify potential challenges and opportunities and provide tailored solutions.
‘This latest agreement enhances our overall tailings offering and enables us to provide our customers with a complete tailings solution. Under the brand name IsoDry, we will continue to offer customers a range of mechanical separation technologies, such as thickeners, filter presses, centrifuges, and vacuum belt filters,’ Charlie Stone, Weir Minerals VP Sales and Business Development-Mill Circuit said.
Weir Minerals has strengthened its tailings team to support the market and ensure that it can provide innovative solutions based on each customer’s specific requirements.
The agreement provides the opportunity for potential future collaboration on technology, harnessing Andritz’s market-leading separation technology in conjunction with Weir Minerals’ minerals and tailings processing technology. Many of these products – Warman® pumps to transport fluid tailings, GEHO® pumps to handle paste, Cavex® hydrocyclones to dewater tailings and the Multiflo® range of dewatering solutions – have been integral to helping miners manage their waste for generations.
Weir Minerals and Andritz have also reiterated their shared commitment to sustainability; it is an essential part of both their business and corporate strategies. Both companies have outlined ambitious plans to reduce their carbon emissions, while their approach to ESG initiatives extends to all aspects of their organisations.
‘Shareholders and stakeholders are rightfully demanding more sustainable mining practices and tailings management is an area where there’s a lot of scope for improvement. Weir Minerals wants to play a central role in changing how the industry thinks about and manages tailings. Ultimately, we believe that sustainable solutions are not only environmentally beneficial, but also reduce operating costs and minimise risk,’ David Almond, Weir Minerals Global Director, Product Management Process said.
‘Weir strives to make our customers more sustainable and efficient; it’s core to our purpose and at the heart of what we do. We believe that embedding sustainability throughout our organisation protects and creates long-term value for our stakeholders and secures the long-term future of Weir. Our approach to tailings management is an extension of our broader corporate strategy. There is scope to make long-lasting, impactful change in how the mining sector thinks about and manages tailings and Weir is proud to be one of the industry leaders,’ Jon Stanton, Weir Group Chief Executive said.

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.

Australia buys Digicel, PNG’s mobile monopoly
Photo credit: Devpolicy by Stephen Howes Yesterday, Telstra announced that it was buying Digicel Pacific. Telstra itself is only paying $270 million, and the Australian government $1.33 billion. Yet, Telstra is obtaining 100% ownership. The deal is certainly an attractive one for Telstra. But does it make sense for Australia, and for the Pacific? Digicel has had a transformational impact in the Pacific, but now has too much market power. As the Telstra release explains, it holds the dominant position in all the Pacific countries in which it operates, except for Fiji, where it is in second place. In Papua New Guinea, which I know best, and which is by far Digicel's biggest market, the company has a 92% share of the mobile phone market. That makes Digicel effectively a monopoly in PNG. And that is why it is so profitable: like any monopolist, it exploits its market power. Australian and PNG researchers have been tracking mobile internet prices in PNG since Australia gifted it a new underwater cable . Their conclusion is that since the completion of that cable in December 2019 to today there has been no decrease in mobile internet prices. The reason is simple: the lack of retail competition. Michelle Nayahamui Rooney, Martin Davies and I last year exposed Digicel PNG’s predatory loan scheme. Digicel lends phone credit to its customers. They pay it back when they next top up. Our estimate is that Digicel made a 17% return from such loans every week, which is equivalent to an unbelievable 351200% a year. Is this really the way in which Australia want to engages in the Pacific – owning an enterprise that keeps prices high for consumers, and rips them off when they are desperate to make a call? Any monopolist is necessarily engaged in a battle between the consumer and their profits. At some point, Telstra will end up going toe-to-toe with the PNG telecom regulator, NICTA, as Digicel has done several times. It’s going to be awkward for both Telstra and the Australian government. Many will welcome the investment as a sign of Australian commitment to the Pacific. However, if we want to invest in the telecom sector in the Pacific, we should be backing alternatives to Digicel, to push prices down and improve services, not buying out the dominant player. Amalgamated Telecom Holdings based in Fiji is the Pacific’s second biggest telecom provider. It is currently planning to enter the PNG mobile market with support from the Asian Development Bank. This is the sort of investment we should be financing. That Australia has bought Digicel shows the extent to which the Pacific is now viewed through a China lens. That’s unfortunate. China is a massive economic power. Its companies will have increasing stakes in economies around the world. That is a fact we have to accept. The Australian government also needs to decide if its only goal is to counter China or if it is still seeks to promote Pacific development. When I was AusAID's Chief Economist, Digicel was the new kid on the block in the Pacific, and it was successfully challenging state-owned telcos that until then had been dominant. In 2006, in Foreign Minister Alexander Downer's flagship Pacific 2020 report, we wrote glowingly about the competition that various Pacific countries had recently started allowing in the mobile phone sector. Our analysis was right then, and remains relevant today. Yet here we are, in 2021, doing the opposite: rather than supporting greater competition in the telecom sector, subsidising the purchase of the incumbent monopolist. The decision to buy Digicel Pacific should be reversed. If it is too late for that, the Australian government should at least – in return for all its cheap and risk-reducing finance – oblige Telstra to operate Digicel for the benefit of the people of the Pacific rather than solely for its shareholders through an agreement that makes it clear that the Australian company is not only expected to return the cheap loan it has been given, but also reduce prices, and end rip-offs.

Taureka Replaced As Managing Director
Isikeli Taureka's position as managing-director (MD) of Kumul Consolidated Holdings (KCH) was terminated by the National Executive Council (NEC) recently. Professor David Kavanamur has been appointed as interim MD until a permanent appointment is made, and Moses Maladina, the current chairman of PNG Power Ltd, has been named as acting chairman. Taureka was removed after 20 months, according to Prime Minister James Marape, due to poor performance by KCH and State-Owned Enterprises (SOEs) and missed national project deadlines. “The reforms of the SOEs were endorsed by the Government in October 2019,” he said “We see it as the most-significant reform programme to be undertaken by any Government since the corporatisation of the state utilities and the creation of the Independent Public Business Corporation (IPBC), now KCH. “Building governance and accountability must go hand in hand with successful project execution. These are viable projects that can fundamentally change the accessibility and affordability of services and benefit the welfare of our people. “Extensive unexplained delays to major projects by KCH and SOEs are not acceptable. The Government understands that SOE issues cannot be immediately resolved as they take time. “That is why the NEC provided well over a year for KCH to work with SOEs to support the development and execution of strategies. We had hoped more would have been achieved during Taureka’s tenure. We regret to take the difficult step of severing the MD’s appointment. However, the NEC felt it had to be done. “The Telikom merger and partial privatisation with majority ownership and board control to be passed onto the super funds, for example, is one major issue the Government has been pushing since 2019 when we took office. “The merger of Water PNG and Eda Ranu is another matter that has been outstanding and not yet resolved. This merger is to take on a subsidiary structure where 20 percent of Eda Ranu is to be owned by Koiari landowners and 10 per cent each by Central Province and the National Capital District. “This decision was taken in 2019 but has not been implemented to date. “As for PNG Power and its continuous performance issues, these have been ongoing and evident. “These are badly-needed reforms within the SOEs and responsive policies have been launched by the Government, yet, very little or no progress have been made. “Out of respect to Taureka as a leading Papua New Guinea son, I had reached out to him for a meeting but there was no response forthcoming. Hence, the announcement of this decision (termination),” he added. Those nominated to crucial positions, according to Marape, must grasp the larger picture and act quickly to fulfill the government's goals.“For others in key leadership roles, whether as chair, members of boards, departments or agency heads, you are not here to pass the time or warm seats. Everyone must step up. “The Prime Minister’s Department is working to take stock of work done. So, if you feel you have not met your key performance indicators, I suggest you start thinking about resigning before the NEC asks you to leave.” According to Marape, Kavanamur had previously served as the chairman of KCH and had a thorough awareness of the organization's issues as well as the government's goals.

Digicel Pacific to be Acquired by Telstra
Telstra has announced that it will buy Digicel Pacific for $US1.6 billion, plus up to an additional US$250 million based on business performance over the next three years, subject to government and regulatory approvals. In its six South Pacific markets – Papua New Guinea, Fiji, Nauru, Samoa, Tonga, and Vanuatu – Telstra, Australia's leading telecommunications and technology company, will continue to invest in and operate the business under the Digicel brand name. Telstra International CEO Oliver Camplin-Warner said the agreement will allow Telstra to expand on Digicel Pacific's regional leadership and increase mobile connectivity in Papua New Guinea. “Denis O’Brien and the Digicel team have built a phenomenal business that’s centred on providing exceptional customer service, the best coverage and leading digital experiences. Telstra will add to these strengths and the team’s local knowledge with our more than one hundred years’ experience connecting the vast expanses of Australia to continue delivering great experiences for Digicel’s customers across the Pacific.” “We have 19.5 million retail mobile customers in Australia and our 4G network is the largest and most reliable in country. It covers some of the remotest parts of Australia – from the coast, to the outback and the Torres Strait Islands, just off the coast of Papua New Guinea. And we’re in the process of building Australia’s largest 5G network that now stretches to more than 240 towns and 75 per cent of the population,” Camplin-Warner said. There will be no employment losses in the region as a result of the transaction, and the present Digicel Pacific team will continue to manage the company on a day-to-day basis. Denis O'Brien, the current owner of Digicel, will continue on the Board of Directors. “We will invest our know-how and capital to further expand coverage and over time bring the benefits of 5G to Papua New Guinea. But we’ll retain the same Digicel brand the people of PNG know and love today with the same team and services they have come to rely on,” Mr Camplin-Warner said. The purchase, according to Camplin-Warner, is in line with Telstra International's expansion plan, which now comprises operations in 20 countries outside of Australia and thousands of clients, including businesses, governments, and some of the world's largest technology firms. “Beyond Australia Telstra also has the most extensive subsea telecommunications cable network in the Asia Pacific. And we’re one of the biggest providers of voice and data services connecting the South Pacific to the rest of the world through our Southern Cross cable.” “Network traffic is growing faster than at any other period of time and digital technology is changing our world. We are at the centre of this, and so is Digicel Pacific. We are committed to delivering the best technology on the best network for PNG,” Mr Camplin-Warner said. The people and businesses of PNG will benefit from Telstra's experience rolling out a world-class 5G network and connecting diverse geographies, according to Colin Stone, CEO of Digicel Papua New Guinea. “Telstra’s network innovation has played a critical part in Australia being ranked first in the global Mobile Connectivity Index which assesses networks based on performance, affordability and availability. We look forward to working with Oliver and the Telstra team,” Mr Stone said. The two firms' ideals, according to Camplin-Warner, were likewise matched. “Digicel Pacific and Telstra are both committed to building a connected future so everyone can thrive and this includes supporting some of the most vulnerable in our communities.” “Digicel Pacific has taken community development to the next level through the Digicel Foundation’s investment in health, education and community-based programs. We look forward to continuing this work, just as we do today with the Telstra Foundation and its commitment to using technology to support young people and help to reduce the digital divide.” “We will also bring a commitment to addressing climate change to help drive better environmental outcomes for the people of PNG,” Mr Camplin-Warner said. Despite the fact that the transaction is funded by the Australian government, Telstra will remain the only owner and operator of the company.
