Here is the introduction of five flotation processes used to the extraction of lead-zinc sulfide ores.. in nature the lead-zinc minerals mainly include lead-zinc sulfide and lead-zinc oxide ore. the lead-zinc sulfide accounts for a large proportion and has the higher industrial application value.
History of sulphide ore flotation dates back to beginning of 20th century. sulphide ores are major sources of base metals like copper lead zinc nickel cobalt etc. beneficiation of these base metal sulphide minerals is predominating through froth flotation technique. this technology has acclaimed importance as a versatile process f.

The ore is the oxide ore of copper lead and zinc the ore has high oxidation rate of pbnearly 50. which contains 3.56 of pb3.86 of zn0.209 of cu. the flotation flowsheet consisting of the scene is part of the mixed flotation—inhibitor zn and pb-cu mix flotation—zn flotation—cu-pb separation.
The pb-zn sulfide ore is often associated with a variety of valuable components such as lead zinc copper sulfur and other useful minerals whose floatability is obviously different which determines the different froth flotation method used in the extraction of lead and zinc sulfide ores.
The polymetallic sulfide ore of copper lead and zinc is widely found all over the world and is often associated with rare metals such as gold and silver. the economic value of the comprehensive recycling of this of ore is large1. the polymetallic sulfide ores of copper lead and zinc are usually processed via flotation and the concentrates .
