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 - Geologypage,Galena is an important ore mineral of Lead. It mainly forms by the hydrothermal process of ore formation. Galena precipitates out of hydrothermal solutions easily when lead ions combine with sulphur ions, which is more likely to occur with declining temperature and pressure.

These ore bodies range from 0.5 million tonnes of contained ore, to 20 million tonnes or more, and have a grade of between 4% combined lead and zinc to over 14% combined lead and zinc. These ore bodies tend to be compact, fairly uniform plug-like or pipe-like replacements of their host carbonate sequences and as such can be extremely profitable,Some beneficiation technology of oxide lead zinc ore,Oxide lead-zinc ore always has a high oxidation rate and a fine dissemination. It coexists densely with oxidized minerals such as limonite. Most of them contain a large amount of native ore mud and easily muddy vermiculite, and sometimes contain soluble salts such as gypsum.(PDF) Evaluation of lead zinc ore tailings by flotation,Evaluation of tailings from processing plants is always an important issue. Lead-Zinc ore tailings containing 3.12% Zn, 3.43% Pb, 0.71 g/t Au and 74 g/t Ag was subject to this study.
