Open full text 2 citations

Abstract

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.
