The Weir Group has issued its half-year results to June 30, 2023, noting some significant achievements across its Minerals and ESCO divisions.

Headline numbers for the six-month period included a 19% year-on-year jump in revenues to £1.3 billion ($1.67 billion) and a 26% rise in operating profit to £212 million.

Weir Minerals continued to execute on key strategic growth initiatives, and during the first half gained market share in its core mill circuit product categories, it said.

The company said: “We converted 100% of our competitive field trials for large mill circuit pumps, and also rolled-out our latest cyclone technology.”

One highlight in the period came at a large Brazilian iron ore mine, where Weir Minerals upgraded the cyclones to its latest Cavex® 2.0 solution. The new cyclones, which are Synertrex®-enabled, have improved separation and increased mineral recovery by more than 400,000 t/y, according to the company.

Cavex 2 cyclones were launched in 2020, introducing new geometric features to offer performance unmatched by any cyclone in operation at that point, the company claimed. The advanced LIG+ design (patent pending) enables the Cavex 2 hydrocyclones to classify up to 30% more feed slurry, while occupying the same footprint as competitor hydrocyclones, according to Weir.

Weir Minerals says it also made good strategic progress in sustainable solutions during the six-month period and delivered year-on-year growth in comminution. New orders included a pebble crushing plant for a large copper mine in South America and a crushing solution for a potash mine in Canada.

The company also said it saw “very encouraging interest” from customers for its Redefined Mill Circuit, securing orders from large copper mines in South America for coarse particle flotation (CPF) pilot circuits, in partnership with Eriez.

“Through this strategic alliance, we have integrated CPF technology with our latest generation Warman® mill circuit pumps and Cavex cyclones to provide significantly improved recoveries and process efficiencies for our customers,” it said. “Once operational in the September quarter, these plants will be important reference sites for the industry.”

Around a year ago, Weir Minerals and Eriez Flotation announced a cooperative agreement to design and develop CPF systems. This allows both companies to better connect the Eriez equipment with the slurry classification and conveying expertise of Weir Minerals, according to Ricardo Garib, Division President of Weir Minerals.

Weir Minerals also launched its new, proprietary digital intelli-solutions for pumps, cyclones and high pressure grinding rolls which, coupled with its Synertrex 2.0 platform, captures critical machine health data and enables remote condition monitoring.

It concluded: “We continued to invest in research and development of our core technologies including new materials and polymers, and upgrades and range expansions for our industry leading Warman slurry pumps.”

Weir ESCO, meanwhile, reported that the number of mines using Motion Metrics™ AI-enabled vision technology increased during the first six months of the year, with new orders including a package of five ShovelMetrics™ and five LoaderMetrics™ systems to be deployed across all large mining machines at an iron ore mine in Western Australia.

“The division made excellent progress in growing market share in mining attachments, with a 37% year-on-year increase in orders,” it said. “A particular highlight included converting four cable shovel buckets from competitor products to ESCO technology for a large North American copper miner.”

The division also provided an update on trials of its proprietary ore characterisation technology, which has been leveraging the BeltMetrics™ solution from Motion Metrics positioned above a conveyor directly after the crusher in the flowsheet at an unnamed mine. As well as using the rugged vision technology Motion Metrics has previously used, the company is also incorporating hyperspectral imaging into the mix for this trial.

It reported: “Field trials of our proprietary ore characterisation technology were successfully completed during the first half. Tests enabled critical data to be collected and validated the performance of the technology in a real-world environment.”

Development has now progressed to the next phase focused on exploring “novel illumination” technologies to enhance minerals characterisation, it added.

New Motion Metrics capabilities and functions were launched during the six-month period, including an upgraded lens cleaning solution that enhances machine vision capability and improves response times.

“Other technology investments included development of a new series of mining attachments that, once launched, will expand our addressable market,” it said.

Weir Minerals, the sole producer of Linatex® premium rubber products, has expanded its rubber manufacturing facility in Batu Caves near Kuala Lumpur, Malaysia, doubling production capacity and enabling faster delivery times to customers.

The site, which sits on 18 acres (7.3 ha), has been expanded to include a new Continuous Rubber Process (CRP2) facility, a new Banbury mixer to manufacture masticated dry rubber and additional rubber presses to support the growth within this area of the business.

The modern manufacturing facility features state-of-the-art equipment that produces Linatex rubber products, a leading rubber used to protect equipment in mining, minerals processing and industrial applications for the global Weir Minerals network. The £13 million ($14 million) investment enhances Weir Minerals’ position as a global supplier, enabling the company to meet the increasing demand for premium rubber products and support its worldwide customer base, it said.

The new facilities were inaugurated by the President of Weir Minerals, Ricardo Garib, Vice President Operations of Weir Minerals, Richard Hinsley, and Managing Director of Weir Minerals Malaysia, Stephen Frendt.

Frendt said: “Our site manufactures Linatex rubber sheet and moulded rubber products for process equipment used in mining and industrial applications. This expansion will allow us to service the growing demand in the market – not just now but for years to come.

“The investment in the CRP2 allows us to increase the production capacity for the high wear and abrasion resistant Linatex rubber sheet. The Rubber Mixing Process expansion, on the other hand, is an upstream vertical integration of the supply chain in which masticated dry rubber compounds such as R55 are manufactured and distributed worldwide from the facility here at Weir Minerals Malaysia.”

The investment is a testament to the company’s focus on material technology, it says, ensuring that Weir Minerals’ customers have access to the best elastomers and supporting continuous product development.

Garib added: “Linatex is a vulcanised natural gum rubber, which is produced through a unique liquid phase proprietary process. Manufactured from a renewable resource, the final product is 95% natural rubber made from the highest-quality latex. Our rubber manufacturing facility is
very significant to Malaysia and to Weir Minerals globally, and continues to showcase our dedication to the environment and sustainable practices.”

In line with Weir Minerals’ dedication to sustainable solutions and practices, the Linatex rubber manufacturing process already has the lowest energy consumption compared with other rubber suppliers to the industry, it claims. A new renewable solar energy system has been installed on site in Batu Caves to further lower the power used in the rubber production process. The solar panels will reduce greenhouse gas emissions by almost 900 t CO2e/y, the company estimates.

Weir Minerals says it is also committed to further sequestering carbon by planting new trees on site and ensuring the natural surroundings are rehabilitated and preserved. All-local tree species were selected for this project after consultation with the local town council.

Hinsley said: “Sustainability is an inherent part of Linatex production, starting with latex being a natural and renewable resource sourced directly from the Hevea Brasiliensis trees, to working with ‘green’ suppliers, to manufacturing. The Continuous Rubber Process has minimal waste, and even mixing requires less energy compared to other rubbers.

“Sustainability is also an important part of our supply chain: we have been investing in Malaysia for a long time, employing local workers, providing community support and partnering with local suppliers, some of whom have been with us for over 30 years.”

Weir and Swiss Tower Mills align on energy efficient comminution pathway

The Weir Group has announced a new alliance with Swiss Tower Mills Minerals (STM) in which Weir will market STM’s vertical stirred grinding mills for coarse grinding applications worldwide.

Integrating vertical stirred grinding mills into Weir’s minerals processing flowsheet will provide customers substantial improvements in throughput and energy efficiency, helping them to meet their productivity and sustainability goals, Weir says.

STM’s vertical stirred grinding technology is proven for energy efficient comminution in the mining market with more than 80 units currently operating in the hard-rock mineral processing industry across the globe, according to the company. It is used within the comminution segment of the minerals processing circuit as part of a series of crushing and grinding processes that create the fine particles from which minerals can be extracted through flotation.

Comminution, as has been well documented, is one of the most energy intensive parts of the mine, accounting for 25% of the final energy consumption of an average mine site.

Weir says it is already a leader in comminution technologies, offering solutions such as Enduron® high pressure grinding rolls (HPGRs) to drive down energy consumption by around 40% for customers.

This new alliance with STM takes things to the next level, offering the mining and minerals industry a proven low energy alternative to traditional high energy consuming tumbling mills, it said. Combining and integrating these energy-efficient technologies into a single, optimised flowsheet will deliver significant reductions in energy use, driving down costs and carbon emissions.

In order to prove the most beneficial flowsheet for specific projects, STM has already supplied two vertical test mills to the Weir Minerals HPGR test facility in Venlo (Netherlands). This will put Weir and STM in the unique position to provide clients combined energy efficient grinding test work of HPGR followed by STM’s vertical stirred mill, they said.

Ricardo Garib, Weir Minerals Divisional President, said: “Weir and STM share the same vision of enabling primary resource providers to produce resources in the most sustainable manner. This is a perfect match of best-in-class technology providers. Integrating STM mills with Weir’s comminution products, which includes Enduron HPGRs and Enduron screens, will improve throughput and help bring substantial reductions in carbon emissions.

“This is a real win-win.”

Fritz Moser, STM Chairman, said “Both the HPGR and the STM vertical stirred mills provide significant energy savings compared to conventional grinding technologies. Our new supply agreement with Weir will enable us to fast track the roll out of an innovative flowsheet using STM mills in conjunction with Weir’s Enduron HPGR.”

Weir Minerals and Eriez Flotation have announced a cooperative agreement to design and develop coarse particle flotation (CPF) systems.

Coarse particle flotation facilitates more efficient separation, while also reducing water and energy consumption and producing safer tailings. It has been proven at the likes of Anglo American’s El Soldado mine, Newcrest’s Cadia operation and Capstone Mining’s Pinto Valley operation, among others.

“This cutting-edge technology is a step-change improvement over conventional flotation systems,” Eric Bain Wasmund, Ph.D., Professional Engineer, Vice President of Eriez Global Flotation Business, said.

The cooperation allows both companies to better connect the Eriez equipment with the slurry classification and conveying expertise of Weir Minerals, according to Ricardo Garib, Division President of Weir Minerals.

“As mining companies look to optimise their plant and processes while also reducing their carbon footprint, we’ll see CPF being more widely adopted,” he said.

“We have an Integrated Solutions team – made up of a diverse range of product experts, process engineers, design engineers and materials scientists, among others – that works closely with miners to deliver reliable solutions that help solve their specific problems. In the current regulatory environment and with an increased focus on ESG issues, miners are being asked to produce more with less and CPF systems are a vital technology that allows them to do that.”

Eriez’s leading products include the HydroFloat® Separator for coarse particle mineral concentration, which delivers the capacity of a density separator while maintaining the selectivity of a flotation device. Using a novel aeration system to disperse fine bubbles into a fluidised-bed environment, the HydroFloat Separator significantly increases the selective recovery of coarse particles by applying flotation fundamentals to gravity separation.

Garib added: “Weir Minerals has a long history of innovative engineering and we’re excited to partner with a company like Eriez because its technology perfectly complements the solutions Weir Minerals currently provides. Ultimately, it’s about delivering the best outcomes for our customers.

“We’re proud of the work we do to harness the latest technologies to efficiently process the minerals that will be essential for a future in which mass electrification will play a vital role in the transition to a low carbon economy.”

“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.

Steve Huff, President Andritz Separation, 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.”

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.

Charlie Stone, Weir Minerals VP Sales and Business Development-Mill Circuit, said: “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.”

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 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, they said.

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 say they have outlined ambitious plans to reduce their carbon emissions, while their approach to ESG initiatives extends to all aspects of their organisations.

The Weir Group says it has won a £95 million ($127 million) order to provide aftermarket components and service to the Iron Bridge magnetite project in Western Australia.

The aftermarket contract follows Weir’s success in winning a record £100 million order for original equipment for the Iron Bridge project in 2019, including its Enduron® High Pressure Grinding Rolls (HPGRs, pictured) that, it says, will enable dry processing of ore and use at least 30% less energy than traditional alternatives.

The Iron Bridge magnetite project is a $2.6 billion joint venture between Fortescue Metals Group’s subsidiary FMG Magnetite Pty Ltd and Formosa Steel IB Pty Ltd located in the Pilbara region, around 145 km south of Port Hedland.

Both the aftermarket order and revenues will be recognised over the seven-year period of the agreement, which starts in 2022, in line with the 22 Mt/y project’s initial production.

Ricardo Garib, President of Weir Minerals, said: “This is another landmark order for Weir. Having helped design an energy and water efficient magnetite processing plant, we are delighted to provide operational support for Iron Bridge from 2022. It is an excellent example of the value that Weir’s innovative engineering and close customer support can create for all our stakeholders and reflects the key role we have to play in making mining operations more sustainable and efficient.”

Weir’s Enduron HPGRs are increasingly replacing conventional mills in comminution circuits, Weir says. In addition to their energy and water savings, they also reduce grinding media consumption, while their wearable components last longer, reducing maintenance costs. Additionally, HPGRs contribute significantly to carbon dioxide emission savings.

Stuart Hayton, Managing Director of Weir Minerals Netherlands, where the Enduron HPGRs are designed and manufactured, said: “This is an important project for Weir and for the broader mining industry. We know comminution is one of the most energy intensive parts of the mineral process and, with our Enduron HPGRs, we have a unique ability to offer significant cost, energy and water savings to customers around the world. As the mining industry evolves, we are commited to continuing to innovate, reducing miners’ costs and environmental impact.”

This latest contract award means Weir now has more than £200 million of orders from the Iron Bridge project including its Enduron HPGRs, GEHO® and Warman® pumps, Cavex® hydrocyclones and Isogate® valves.

To support the project and future growth, Weir says it will build a new service centre in Port Hedland, Western Australia, thereby providing employment and training opportunities in the area, with a particular emphasis on supporting greater Aboriginal representation in the broader mining workforce.

The Weir Group says it has been awarded a £100 million ($123 million) order to provide industry-leading energy saving solutions to the Iron Bridge magnetite project, a joint venture between Fortescue Metals Group and Formosa Steel IB.

The order, which includes a range of Weir crushing and pump equipment including Enduron® high pressure grinding rolls (HPGRs) and GEHO® pumps, will reduce energy consumption and wet tailings waste by more than 30% compared with traditional mining technologies, according to the equipment manufacturer.

The Iron Bridge project, 145 km south of Port Hedland in the Pilbara region of Western Australia, is a $2.6 billion investment in premium magnetite iron ore reserves with annual production, when the mine is fully operational, of 22 Mt/y of 67% Fe concentrate. Delivery of the first ore is expected in 2022.

When the mine build was approved back in April, Fortescue CEO, Elizabeth Gaines, said the innovative design for the project, which included the use of a dry crushing and grinding circuit, “will deliver an industry-leading energy efficient operation with globally competitive capital intensity and operating costs”.

A pilot project to verify the Iron Bridge project design involved processing 1 Mt of ore through a full scale HPGR and air classifier, according to Fortescue.

Weir Group Chief Executive Officer, Jon Stanton, said: “We are delighted to have secured this landmark contract, which is Weir’s largest-ever individual mining order.

“Fortescue challenged us to help create one of the most energy and cost-efficient magnetite ore processing facilities in the world. Our engineers have worked relentlessly to design a solution that is truly innovative – delivering significant energy, water and cost savings. This is a great example of working in close partnership with an ambitious customer who shares our passion for using innovative engineering to make mining more productive and sustainable.”

Ricardo Garib, President of the Weir Minerals division, added: “Our team are really enjoying working with Fortescue. Our engineers relish a challenge and it has been great to work on a project that demonstrates the substantial cost and environmental savings that our range of solutions can offer.

“As more mines look to increase productivity, we look forward to even more opportunities to leverage our combination of passionate people, innovative solutions and comprehensive global service capability.”

Weir’s Enduron HPGRs are increasingly replacing conventional mills in comminution (crushing, screening and grinding) circuits because of their substantially lower energy consumption and potential for significant total cost of ownership reduction, Weir says.

“Not only do they require as much as 40% less energy than traditional alternatives, but their wearable components last much longer and the maintenance time required to replace worn out parts is significantly lower.”

The company outlined the reasons why companies are turning to Enduron HPGRs in a blog post earlier this week.
