The AC filter is a response to increasing demand for advanced and sustainable battery metals processing technologies and is part of Metso Outotec’s Planet Positive portfolio.
The modular AC filtration technology is designed for smaller side streams of copper and other metal-loaded aqueous streams. It is specifically suited for efficient organics removal before the electrowinning and crystallisation processes. The AC filter uses the proven design and operation philosophy of the Metso Outotec DM filter product family and is suitable for both greenfield and brownfield installations.
The AC filter’s benefits are increased end-product yield and quality, increased recovery and recycling of valuable process chemicals, a cost-effective and modular design and low energy consumption, due to low pumping pressure. There is also reduced water consumption with optimised back washing and it is safe to use and operate, due to sealed pressure vessel and piping
Mika Vuorikari, director of Industrial Filtration at Metso Outotec, said: “Together with the Dual Media (DM) filter, Metso Outotec now has a complete filtration portfolio for solvent extraction (SX), electrowinning (EW) and crystallisation processes.”
