Study of Lead flotation test in oxide Lead-Zinc Ore

摘要

This paper studied an technological process of recovery of Pb and Zn from a difficult to choose high oxidation Lead -Zinc deposit. By mineralogy process study shown, the run-of-minc grade of Lead was 4.09%, with the oxidation rate of 88.26%. The optimal grinding fineness was about to 85.68%. Use the best reagent combination which obtained by condition test, the final results was that the grade of Lead concentrate was 35.6% and the recovery rate was 78.73%, included silver 564 g/t;;the grade of the Zinc concentrate was 42.50%, and the recovery rate is 83.65%.
