Lead and Zinc Smelting
Lead and zinc can be produced pyrometal- lurgically or hydrometallurgically, depending on the type of ore used as a charge. In the pyromet- allurgical process, ore concentrate containing lead, zinc, or both is fed, in some cases after sin- tering, into a primary smelter. Lead concentra- tions can be 50–70%, and the sulfur content of sulfidic ...
