The flotation of mixed lead zinc ore can be carried out in lead sulfide lead oxide zinc sulfide zinc oxide lead sulfide Zinc sulfide lead oxide. Jaw Crusher, Cone Crusher : crush ore to a smaller size, make the target minerals and gangue minerals dissociated.
We mine and process zinc and lead ores in the key mining regions of Australia, South America, Kazakhstan and Canada. And, we smelt and refine zinc and lead at processing operations in Australia, Canada, Spain, Italy, Germany, the UK and Kazakhstan. We also source and recycle zinc and lead materials in Europe and North America.

The flowsheet above was designed to treat economically approximately 200 tons in 24 hours of a low grade dump ore containing lead and zinc values as well as some silver in both sulphide and oxide form.
Energy and Environmental Profile of the U.S. Mining Industry 18.104.22.168 Lead and Zinc Ore Milling Treatment of lead and zinc ores begins with milling. Milling is a multi stage crushing and grinding operation. It involves coarse crushing followed by wet grinding. Crushing is usually a dry operation that utilizes water sprays to control dust.
The lead was extracted from the mineral galena, and the zinc was extracted from the mineral sphalerite. In general, mining was done underground, using the room and pillar method, in which room shaped areas were mined and large pillars of rock left in place for roof support.
