Metso Outotec adds to Planet Positive range with Activated Carbon filter for battery metals

Metso Outotec is launching the Activated Carbon (AC) filter for, it says, efficient recovery and recycling of valuable battery chemicals.

The energy- and water-efficient AC filter responds to the market’s increasing demand for advanced and sustainable battery metals processing technologies and is part of Metso Outotec’s Planet Positive portfolio, it said.

Planet Positive is Metso Outotec’s all-encompassing approach to sustainability. It covers the environmental, social and financial aspects of sustainability, focusing on the positive impact on the environment and people through further growing its sustainable offering through products that are demonstrably more energy or water efficient than the market standard, or help customers achieve other priorities such as circularity and safety, as well as services that help customers improve their productivity.

Mika Vuorikari, Director of Industrial Filtration at Metso Outotec, said: “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 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.”

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 already proven design and operation philosophy of the Metso Outotec DM filter product family and is suitable for both greenfield and brownfield installations, the company added.

Benefits of the AC filter outlined by Metso Outotec include:

  • 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; and
  • Safe to use and operate, due to sealed pressure vessel and piping.
