In the beneficiation process, the sulfide lead-zinc ore is mainly flotation. Among them, the proportion of zinc ore in most lead-zinc ore is higher than that of lead ore. Therefore, in the actual process, the method of "suppressing zinc and floating lead" is generally adopted. Main principles to deal with lead-zinc sulfide ore.Web

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 [1], [2], [3]; however, there is an urgent need to handle the oxidized ore due to the gradual depletion of the sulfide ore.Web
