Metso is expanding its polishing filtration product family with the addition of the GM (Glass Media) filter, designed to, the OEM says, remove insoluble organics in battery metals processes by using very efficient and patented coalescing media.

With its cost-effective and modular design, the GM filter increases the recovery and recycling of valuable process chemicals.

Mika Vuorikari, Director of Industrial Filtration at Metso, said: “The GM filter is an ideal choice when insoluble organics need to be removed and recovered. Thanks to its efficient coalescing media for hydrometallurgical applications, the GM filter can perfect the removal and recovery of insoluble organics at a much higher velocity than the traditional coalescing medias. In applications where an Active Carbon (AC) filter needs to be used for dissolved organics adsorption from the process, the AC filter’s efficiency and media lifetime can be improved by utilizing a GM filter in front of it.”

The Metso GM filter is designed for variable sizes of process streams and its modular design makes it easy to expand to meet plant process requirements. It also optimises back washing with filtered process liquid and circulates back to the process, ensuring that water consumption is kept to a minimum. The low pumping pressure of the filter also results in lower energy consumption.

Together with the Dual Media (DM) and Active Carbon (AC) filters, Metso has a complete filtration portfolio for SX electrowinning and crystallisation processes. Strong know-how and experience from the hydrometallurgical industry allows Metso to design industry-leading filtration solutions for battery minerals processing. Metso has delivered more than ninety DM and AC filters to metallurgical SX processes globally.
