摘　　要：本研究根据流精矿中金矿物的嵌布状态和载金矿物的特性，从理论和实践两方面进行了较深入的探讨，确定了最易实现工业化的浮选流程，获得了良好的选矿指标。在原硫精矿含铜０．６７％，金５．０１ｇ／ｔ，银１７．２３９／ｔ，硫３５．１７％的情况下，经氧化浮选后，可获得铜金精矿：βＣｕ＝１５．５９％、βＡｕ＝１１２ｇ／ｔ、βＡｇ＝２１０ｇ／ｔ、εＣｕ＝７７．３％、εＡｕ＝７４．８８％、εＡｇ＝４０．７％的好指标。尾矿（硫精矿）中βｓ＝３５．４％、εｓ＝９７．３１％、可作为硫精矿出售。Based on the embedment conditions and characteristics of gold minerals in sulfur concentrate, the most realizable flotation process flow in commercial scale to recover gold, copper and silver from sulfur concentrate was determined through profound study and investigation theoretically and practically, acquiring favorable index in this paper, Through oxidation flotation of originated sulfur concentrate containing Cu 0.67%, Au5.01g/t, Ag 17.239/t and S 35.17%, the copper-gold concentrate containing.Cu 15.59%, An 1129/t and Ag 210g/t are earned in which the recovery rate of copper is 77.3%, An 74.88% and Ag 40.7%.The tailing containing 35.42% S in which the recoyery rate of sulfur is 97.31%can be regarded as sulfur concentrate to be sold.
