Abstract:
      The ore is the oxide ore of Copper lead and zinc,which contains 3.78% of Pb,3.92% of Zn,0.303% of Cu.The ore has high Oxidation rate of Pb,nearly 50%.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 effectice. 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 17.85% of Cu,7.61% of Pb,and lead concentrate which contains 2.65% of Cu,53.90% of Pb.
