, electroplating and battery. It is extracted from the by-products of zinc metallurgy among which copper-cadmium slag, cadmium-rich dust and spent Ni-Cd batteries are the main raw materials[1-6]. Pure cadmium can be recovered through solvent extraction, electrolysis refining or vacuum distillation[7-15]. The metal elements in copper-cadmium slag are zinc, cadmium, copper and their oxides with a little......
