Weir Mineral partners with Eriez to offer coarse particle flotation systems


The new technology is used in Eriez’ HydroFloat Separator and makes the coarse particle separation process more efficient

Global mining solutions provider Weir Minerals has partnered with Eriez Flotation to design and develop coarse particle flotation (CPF) systems, the companies have announced.

Course particle flotation allows for more efficient separation, while reducing water and energy consumption and producing safer tailings. As a specialist in this area, Eriez’ range of 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, a statement explained.

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

Earlier in August, Sandvik said it won a $32mn order for battery-electric mining equipment. Epiroc also said it had completed its acquisition of drill and spare part specialist RNP México.

The agreement also enhances Weir Minerals’ ‘all-of-mine’ capabilities from the pit to the processing plant, with leading brands such as Warman pumps, Cavex hydrocyclones, GEHO positive displacement pumps, Linatex rubber products and Enduron HPGRs.

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

He concluded, “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.”
