The big batteries are crushed, to split the wrapper from the battery powder. Once the wrapper cleaned, we recycle the paper, the plastic and we obtain iron slag and non ferrous, meanwhile from the batteries powder, once filtered the solution, we initially recycle graphite and manganese oxide and finally after hydrometallurgical treatment we obtain mercury, zinc, copper, nickel, cadmium, manganese salts and zinc solution.
The case batteries are introduced in the distiller without crushing them previously. The condensation post allows to obtain mercury of high purity, higher than 96%.
