  • LEAD ZINC EXTRACTION PROCESSES

    are used for production of lead zinc depending on the type of raw material used as a charge. In the pyrometallurgical process, ore concentrate containing lead, zinc, or both is fed, in some cases after sintering, into a primary smelter. Lead concentrations can be 5070%, and the sulfur content of sulfidic ores is in the range of 1520%.
