6 Lead and Zinc. Lead and zinc ores are usually found together with gold and silver. A lead-zinc ore may also contain lead sulfide, zinc sulfide, iron sulfide, iron carbonate, and quartz. When zinc and lead sulfides are present in profitable amounts they are regarded as ore minerals. The remaining rock and minerals are called gangue.

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
