Abstract Scope |
Compared to other electronic goods life spam of children’s toys are very less, which resulted in the generation of huge amount of batteries and environmental pollution. Initially the batteries are discharged, dismantled, crushed and physically beneficiated to get black powder, metallic fraction and plastics. Further, the black powder of batteries was processed for systematic leaching studies and found 95.6% Mn and 86.05% Co were leached in 2 mol/L H2SO4 at 25 oC in 120 min using the 10% H2O2(v/v) as an oxidant, while maintaining the pulp density 75 g/L. From the leach liquor at various pH 5-8 and above 12, the oxides of Co and Mn were obtained, respectively. The developed process has potential to be transferred in an industry after scale-up studies. |
