Abstract: 
Cadmium can be separated by hydrometallurgy and pyrometallurgy methods. In this research, the wasted cake of zinc factory called nickel- cadmium cake was analyzed, and cadmium was separated by pyrometallurgy method. This cake was heated with a suitable amount of sulfur in the furnace, so soluble cadmium sulfate (CdSO4) was produced. The optimum amount of sulfur consumption, furnace temperature and permanent time were determined by measurement of recovered cadmium value.
