Zinc Ore Sulphide

Two processes are used to produce metallic zinc from the ore concentrates that are not subjected to caustic soda leaching In one process the ore concentrate containing zinc sulfide is roasted in the presence of air to produce zinc oxide which is combined with coke or coal and retorted to approximately 1100 176C to produce metallic zinc
