Metso Outotec says it will supply unique sustainable screening technology for an iron ore project in the Southern Hemisphere.

The order for the product screening and scalping application covers 12 Metso Outotec BSE Series™ (Banana Screen Elliptical) tandem screens and 4 MF Series™ screens, all equipped with 305PS screening media. In addition, the contract covers Metrics monitoring system for screens, expert support and installation services, the company says.

Metso Outotec explained: “The need to reduce water in iron ore production and other minerals processing is a critical global challenge. The innovative and patented BSE Series screens enable iron ore processing even with higher natural moisture content without adding water.”

The order value, which is not disclosed, has been booked in Minerals segment’s September quarter orders received. The start-up of the project is scheduled for the first half of 2024.

Jouni Mähönen, Vice President, Screening business line, Metso Outotec, says: “We are pleased that the customer chose Metso Outotec for sustainable screening solutions for their process. The BSE screen is an outstanding option for their needs. The elimination of process water ultimately results in lower processing costs, increasing the customer’s competitiveness and profitability in the iron ore global markets.”

Results the customer can expect after implementation, according to Metso Outotec, include:

  • BSE Series screens, which are part of the company’s Planet Positive solution, enable elimination of process water in the screening process;
  • A 93% reduction of the plant’s overall water consumption, elimination of the need for tailing dams;
  • Reduced energy consumption from the entire plant compared with the wet screening process: 18,000 MWh/y electricity saving;
  • 30% increase in screening capacity compared with traditional screening;
  • Increased safety during media change-outs using the Hammerless Attachment system; and
  • Reduced capital expenditure due to the adoption of high-performing BSE screens.

New Weir Minerals Sand Wash Plant to boost recoveries

Weir Minerals has released a complete sand wash solution that draws on its long experience in the sand and aggregate industry.

The Weir Minerals Sand Wash Plant comes with Linatex® lining, produces more saleable product than conventional sand screw plants, with fewer moving parts, and has an optimised process that produces a drier, higher-quality product with less fines, according to the company.

The solution has already proven effective at sites like Coimbatore Minerals in Tamil Nadu, India, Weir says, where a custom-built wash plant reduced its total cost of ownership by 51%, while offering a 23% reduction in fines that helped the company consistently meet the industry’s high standards for a saleable product.

Bruce Cooke, Global Product Manager – Sand Wash Plants for Weir, said: “We know the most important thing for quarry operators in washing is recovering as much sand as possible to maximise their sales, which is why we’ve designed an integrated solution for washing their product, with a hydrocyclone which can deliver greater recovery than sand screws. In addition, every component has been selected by our expert engineers for its long-service life, interoperability and ease of maintenance.”

The compact solution features a range of Weir Minerals equipment designed for high efficiency in sand and aggregate applications, including Warman® WGR pumps, Cavex® hydrocyclones, Enduron® dewatering screens, Linatex hoses and Isogate® knife gate valves.

The Warman WGR is a popular pump in the sand extraction industry, according to Weir, combining top of the line hydraulic design with an adjustable impeller, long bearing life and a simplified wet end, making replacement predictable and cost effective.

Precision moulded and lined, Linatex premium rubber is used for wear zones throughout the plant due to its proven wear performance in wet sand applications in operations around the world, Weir said.

Cavex hydrocyclones provide “exceptional classification efficiency” thanks to their unique 360° laminar spiral, delivering more saleable product than a sand screw solution would, the company said. Enduron dewatering screens, meanwhile, reliably separate product with a high degree of efficiency. And, finally, Isogate knife gate valves contribute to the plant’s straightforward maintenance.

Surendra Menon, President, Weir Minerals India, said: “For the new sand wash plant, we focused on making it quick and easy for quarry operators to get up and running. Its straightforward design means it can be assembled in just two days while its compact skids make it easy to drag into any operation.

“Efficient, reliable and easily integrated into flowsheets, we think the plant is a game changer for quarry owners.”

Schenck displays continental comminution offering with Peru copper contract

Schenck Process has won a contract to design manufacture, supply and commission vibrating screens and feeders for the greenfield Mina Justa copper project, in Peru.

The order will see Schenck business units on four continents combine to deliver seven banana screens (across three models), five diverging pan feeders and one grizzly feeder.

Mina Justa, owned by Minsur and Empresas Copec through holding company Cumbres Andinas, is slated to produce around 100,000 t/y of copper when fully ramped up.

The screens and feeder contract will see all design completed at Schenck’s vibrating equipment design centre in Sydney, Australia, manufacture and testing in the company’s Chinese plant, custom-made screen panels from the South Africa production facility and commissioning by the aftermarket services team in Chile. The project is being managed and coordinated by the Australia-based Project Management team, Schenck said.

The screens include several mechanical and operational improvements developed on a prototype vibrating screen now undergoing site testing at an iron ore mine in Western Australia, according to the company.

“The five larger screens feature laminated side plates to maintain structural integrity and reduce stress concentrations associated with the projected process tonnages,” Schenck explained. “Additionally, machined transition flanges are welded in a low stress area to the cross beams to actively reduce fatigue, and a unique spring removal system has been fitted to facilitate and reduce downtime during spring change-outs.”

The six feeders have been designed to account for site conditions and feature a more robust design. They are also equipped with exchangeable liners and an upgraded transition hopper to improve operational availability and performance, the company said.

Each of the vibrating feeders and screens for Mina Justa is equipped with CONiQ, the company’s proprietary continuous six-dimension condition monitoring system, to track and alert operators to abnormal operating conditions. Feeder control systems have been electronically aligned with the screen’s installation, Schenck added.

Project manager, Lauren Williams, said: “This is a truly international project and, from our point of view, it is the best way to give our customer the equipment that will deliver higher process efficiency and longer service life.

“Although based on standardised platform designs for screens and feeders, each unit has been subject to a customising process to meet site and processing capacity requirements. We are delivering an integrated package of screens and feeders to optimise availability and productivity and represent the best value for money.”
