Copper-Lead-Zinc ores

Copper-Lead-Zinc ores

Therefore the standard Cu-Pb-Zn flotation practice involves an initial flotation of a Cu-Pb bulk concentrate followed by two parallel circuit stages of copper-lead separation and separate zinc flotation from the bulk flotation tails. As described in the lead-zinc ore processing section, zinc sulphate and metabisulphide sphalerite and pyrite .

Lead and Zinc

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.

BENEFICATION OF LEAD & ZINC ORES

BENEFICATION OF LEAD & ZINC ORES

sulphides are selectively floated from the ore followed by activation and separation of zinc in case of complex lead-zinc ores. Bulk flotation followed by separation of lead and zinc differential flotation is not quite uncommon. Table 3.5 at the end of this chapter, summarizes the benefication results of lead & zinc Ores studies.
