Two dyads we...

In this paper, we propose a hydrometallur-gical procedure to treat spent Ni-Cd batte-ries using organic acids as leaching agents. The electrode materials of the batteries were extracted and leached combi-nation acetic, citric, sulfuric their mixtures in two-stage selective scheme. This aimed recover metal-bearing solid products. leachates treated by evaporation/crystallization or chemical preci...
