Characteristics of lead zinc copper sulfide ores are many kinds of minerals; useful minerals dissemination size fine, and dense symbiotic; floatability of galena and copper sulphide minerals is very close; sphalerite, pyrite and pyrrhotite It is easily activated by copper ions eluted from secondary copper minerals in the ore; even if the same mineral is often affected by the degree of oxidation, its floatability is difficult, so it is difficult to sort the ore. A lead-zinc ore fluorite mine genus warmed liquid metal filled in the multi-bit low-DEPOSIT puppet, metallic minerals galena, sphalerite and chalcopyrite, and small amounts of pyrite. The non-metallic mineral is fluorite, and the gangue mineral is mainly quartz . Metallic minerals have a coarser grain size and are a better choice of ore. The mine selection plant uses copper and lead partial mixing to separate and mix and select tailings to sequentially float zinc and float fluorite, and recover four useful components of copper, lead, zinc and fluorite. When copper and lead are mixed, ZnSO4+Na2S2O3 is mainly used to suppress sphalerite. Tests and production have shown that the addition of a small amount of cyanide (about 5 g/t) has a significant effect on reducing the zinc content of the mixed concentrate. In the sweeping operation of the mixing cycle, the addition of 30 g/t of activated lead oxide to promote the recovery of lead is advantageous. When separation of copper and lead, after removal of activated carbon by weight sodium inhibitory drug of chromium, lead, supplemented with a small amount of copper floating pine oil, activated charcoal and sodium dichromate as long as there is sufficient duration of action (approximately for 30 min), the copper can lead Better separation.
