In general, the most difficulty of the polymetallic sulfide ores separation is the separation among several kinds of ores, especially those low-graded ores with complex embedded features. Therefore, it''s a significant step for separating lead-zinc, copper-zinc, copper-lead to choose right flotation reagents.
A kind of complex Pb-Zn ore has been studied. The run-of-mine grade of Lead was 2.84%, with the oxidation rate of 90.95%. And the grade of Zinc was 3.22%, with the oxidation rate of 87.9%. The optimal grinding fineness was about to 94.6%. Use the best reagent combination which obtained by condition test, the final results was that the grade of Lead concentrate was 23.41% and the recovery rate ...
