The market is increasing its demand for advanced and sustainable battery metals processing technologies. Metso Outotec has responded to this global demand by launching the Activated Carbon (AC) filter for efficient recovery and recycling of valuable battery chemicals. It is both energy and water efficient.

“This launch will strengthen our capability to serve a large variety of industries and processes. Together with the Dual Media (DM) filter, Metso Outotec now has a complete filtration portfolio for solvent extraction (SX), electrowinning (EW) and crystallisation processes. We have strong know-how from the hydrometallurgical industry with more than 50 successful filtration solutions references from SX and crystallisation processes globally,” says Mika Vuorikari, Director of Industrial Filtration at the company.

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 new product utilises the already proven design and operation philosophy of the company’s DM filter product family and is suitable for both greenfield and brownfield installations.

Benefits of the AC filter:

  • Increased end-product yield and quality
  • Increased recovery and recycling of valuable process chemicals
  • Cost-effective and modular design
  • Low energy consumption, due to low pumping pressure
  • Minimised water consumption with optimised back washing
  • Safe to use and operate, due to sealed pressure vessel and piping
