Finnish mining equipment and technology company Metso Outotec has introduced the DM1000 polishing filter to its Dual Media (DM) filter product family.

The compact energy- and water-efficient Metso Outotec DM1000 polishing filter is especially designed for removing and recovering organic compounds and solids in small stream feeds in battery chemicals processes. Its modular design also makes the filter is easy to expand for larger process flows.

The DM1000 can be used as a traditional electrolyte filter in extraction processes, as well as in metal crystallisation processes for feed flow purification prior to crystallisation.

The company stated that its benefits include: low energy consumption due to low pumping pressure; reduced water consumption due to back wash with filtrated process liquid; efficient recovery of organic compounds back to processing; easy expandability with a compact, fully modular design that features 1-4 filters in a row; easy transport, as filters can be packed and transported in standard sea containers; quick and safe site installation as the filter comes ready assembled on a mounting skid; and fully automatic operation that contributes to overall safety.

Mika Vuorikari, director of industrial filtration at Metso Outotec, said: "Since the launch of our first Dual Media filters some years ago, we have delivered almost 50 DM and DM AC filters for hydrometallurgical extraction and crystallisation processes. We have delivered hundreds of polishing filters to the mining, chemical, and hydrometallurgical industries around the world. 

"Adding the modular DM1000 filter to our offering caters to the special needs of the rapidly growing battery industry, where sustainable high-quality filtration is needed to ensure increased production capacities and high-quality end products."

The Metso Outotec DM1000 polishing filter for battery chemicals is part of the company's Planet Positive sustainability offering, which was launched in March and focuses on the most environmentally efficient technologies in the company's current portfolio.
