2021-7-20 In the practice, the flotation method, gravity separation method and combined beneficiation method can be used for copper - lead - zinc sulfide ore. Among them, the flotation method has become the main separation method of copper, lead and zinc sulfide ores because of its good separation effect on various complex polymetallic co-biogenic minerals.

Which flotation scheme used in the differential copper-lead bulk concentrate separation is generally and often dependent upon which mineral has the greater mass in the bulk concentrate. Whichever mineral constitutes the lower bulk concentrate mass will be floated away from the other mineral which is depressed for flotation selectivity reasons.

The ore is the oxide ore of Copper lead and zinc, The ore has high Oxidation rate of Pb,nearly 50%. which contains 3.56% of Pb,3.86% of Zn,0.209% 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”. But the Cu-Pb separation was not effective.

2013-3-1 1. Introduction. In the flotation of complex sulfide ores, the two methods most widely used for the separation of economic amounts of copper and lead are presents as the following: (1) bulk copper/lead flotation followed by copper/lead separation; (2) sequential copper/lead flotation .The sequential separation has some disadvantages, for example, large reagent dosage, complex
