, 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... to 3-4. Finally, pure cadmium metal is deposited by electrolysis. The process for cadmium extraction is complicated and also needs a large quantity of zinc powder. Some studies have shown that copper......
