The process is identical in principle to the flotation of other minerals. The figure on the right is a simplified version of a Pb/Zn flotation circuit. The main difference in lead/zinc flotation is that zinc is usually depressed while lead (and copper) is floated. The tailing from the lead flotation circuit is the feed to the zinc circuit.get price

Usually, lead is found in conjunction with other metals such as silver and zinc. Lead materials are mined as a by product of these other more valuable metals. Extracting the lead materials from the ore is a multi-step process. First the lead ore is ground into small particles that are less than 0.1mm, giving the ore a texture similar to table salt.
Mar 15, 2020· 1. Introduction. Zinc ore exists as both oxidized zinc and zinc-sulfide ore. Zinc is extracted primarily from the zinc-sulfide ore because it is easier to process by flotation than oxidized zinc,, ; however, there is an urgent need to handle the oxidized ore due to the gradual depletion of the sulfide ore.Consequently, the development of methods for processing oxidized zinc ore has become a
