Study on Mineral Processing Flowsheet of a Certain Low Grade Pb-Zn Sulphide Ores

Abstract:

In light of the characteristics of Pb-Zn sulphide ores with fine dissemination size, close intergrowth and contain large number of slime,a new flotation flowsheet is containing lead preferential flotation,ammonium dibutyl dithiophosphate as collector,Na₂CO₃ as pH modifiers, and ZnSO₄ as depressor. Then zinc is recovered by using CuSO₄ as activator, butyl xanthate as collector, successfully realizing the separation of lead and zinc .The grade of lead concentration is 50.60％,containing 3.93％Zn. The recovery of lead is 87.78％.In addition, the grade of zinc concentration is 47.75％, containing 0.48％Pb and the recovery of zinc is 88.58％.
