【Process Introduction】

Copper-lead-zinc sulfide ore is also sometimes called complex polymetallic sulfide ore.Common main metallic mineral are chalcopyrite, galena, sphalerite, pyrite, etc.Mineral component is complex.For close symbiosis, disseminated fine grain size and uneven copper-lead-zinc sulfide ore, it generally adopt bulk-selective flotation process . separate all sulfide minerals ,and then separate the mixed concentrate fully or partly.After coarse grinding is  bulk flotation,elect all valuable mineral,such as Copper, lead and zinc into mixed concentrate and abandoned tailings will be left.The mixed concentrate regrinding and then selected or isolated, this can save a lot of grinding costs, flotation machines and flotation reagents.
