Abstract
In order to efficiently recycle waste industrial nickel-cadmium batteries, anodic and cathodic materials were crushed by a cut mill and classified by sieves. We used wet magnetic separation method for eliminating iron components from the crushed powders. In addition, the acid leaching test for the obtained anode and cathode powders was carried out under various conditions by means of the wet process. At the optimum leaching conditions with 2.0 M $H_2SO_4$ at $90^{\circ}C$, 15 wt $H_2O_2$ and L/S=20 for 3 hours, the leaching efficiency of nickel and cadmium was 99%, respectively.
