Full-scale testing of Metso VPX filter for tailings dewatering started in Brazil

Press release

May 6, 2020

In 2019, Metso launched Tailings Management Solutions (TMS), its response to the global challenge of managing mining tailings efficiently. Metso views the dewatering of waste as the future of mining, allowing the removal of the water and its reuse in the plant itself or restoration to nature. The latest development took place at Metso's facilities in Sorocaba, Brazil, where the first full-scale tests of the Metso VPX filter started in March 2020.The unit will process ore samples sent by several mining companies from Brazil and Latin America.

"This is not a laboratory test, but filtration in industrial scale conditions using VPX technology, which has the capacity to process high volumes of ores", said Rodrigo Gouveia, Vice President, Tailings Management Systems, Metso. “Tailings dewatering is technically and economically a viable option for today and the future. Dry stacking is widely acknowledged to be the safest, most sustainable option for tailings storage. We see that there is a strong demand for short- and medium-term technical solutions.”

Fausto Rezende, Metso’s mining equipment sales director and in charge of TMS in Brazil, highlights that there is another potential aspect to the adoption of tailings management: legacy dams. "We can develop projects for the dredging and concentration of the tailings and in many cases, it is possible that this operation is more economically viable than virgin ore," he said.
