Zinc and manganese extraction from zinc-carbon and alkaline Zn-MnO2 batteries
Original language description
This paper deals with zinc and manganese extractions from electrode materials obtained from spent alkaline and zinc?carbon household batteries. After separated dismantling these batteries, the undersize fractions - 10 mm with 21% Zn, 34% Mn and 0,12% Fefor alkaline batteries and 21% Zn, 26% Mn and 1,62% Fe for zinc?carbon batteries, respectively were obtained. To determine the leachability of electrode materials size fractions (mm) - 10 + 4; - 4 + 2; - 2 + 1 and - 1 were prepared. Size fractions obtained from alkaline batteries contained 17?30% Zn, 27?40% Mn and from zinc-carbon batteries 18-25% Zn, 19?25% Mn. Leaching tests were performed with undressed and ground samples of the size fractions obtained. All samples were water?leached to remove alkaline metals and/or chlorides and then processed in 15% H2SO4 to establish leaching kinetics. The extraction efficiencies of Zn and Mn determined for alkaline batteries moved from 80% to almost 100% Zn and from 19% to 25% Mn and for zinc?car
