Utilization Of Mn-Zn System Batteries

Recycling technology of spent Mn-Zn system batteries has been worked out and tested in laboratory scale. The proposed technological scheme includes the following basic operations: breakage of batteries, hydro-vibrated treatment of broken up mass, electrolysis by using alkali electrolyte. This method enables extracting of 200-220 kg zinc in powder form, of 300-350 kg manganese concentrate and of 130 kg steel in the form of scrap per tone of broken up batteries.
