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.

Calbayog City coastal road project 83% done
A portion of the Calbayog City Coastal Road project in Calbayog City. The project, which is up for completion in 2025, is now 83 percent complete, the Regional Development Council’s regional project monitoring committee reported on Monday (Oct. 18, 2021). (Photo courtesy of Mel Senen Sarmiento) About 83 percent of the Calbayog City Coastal Road Project is now completed after four years of implementation, the Regional Development Council’s regional project monitoring committee (RPMC) reported on Monday. Construction of the PHP1.16-billion project meant to curb traffic jams in Calbayog’s commercial district has been implemented since 2018. It involves the construction of a road, embankment, and bridge. The government is eyeing to complete the project in 2025. “The construction of the Calbayog City Coastal Road aims to create alternative routes in the city to decongest traffic in Calbayog City proper. However, certain segments of the already funded network have yet to break ground,” the RPMC reported. It will start with the construction of a bridge across the Calbayog River since the work will affect the docking of motor boats carrying passengers and products to island communities. The Department of Public Works and Highways (DPWH) and Philippine Ports Authority will find a spot as a temporary dock for the motor boats. “Calbayog City is a fast-growing commercial hub. With its flourishing economy comes the need for bigger and better thoroughfares to accommodate the increasing traffic volume and weight,” the DPWH Samar first district engineering office said in a separate statement. From 2018 to 2021, the project’s work is centered on the construction of embankment and road with a total allotment of PHP1.14 billion. Of the total, PHP333.71 million was released in 2018, PHP281.07 in 2019, PHP268.52 million in 2020, and PHP265.76 million in 2021. The multi-year project that will build a 4.67-kilometer road and bridge will connect the villages of Rawis, San Policarpo, Aguit-itan, allowing vehicles to by-pass the busy road of Calbayog City’s commercial district.
