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.

Flotation Process of Copper Sulfur Ore 1. Priority flotation. Generally, the copper is first, and then the sulfur is floated. The pyrite content in the ore is relatively high for massive copper-containing pyrite. High alkalinity (free CaO content >600~800g/m3) and high xanthate dosage are often used to suppress the pyrite by floating copper.
