Research on Separation of Copper-lead mixed Concentrate

摘要

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.After trials,we eventually developed the flotation process--that is once rough concentration,cubic concentration and twice scavenger concentration,the process can obtain copper concentrate which contains 17.87％ of Cu,7.63％ of Pb,and lead concentrate which contains 2.67％ of Cu,53.93％ of Pb.
