摘　　要：针对微细粒浸染型原生金矿,矿石为低硫化物,含砷、炭难选冶金矿石,介绍了采用浮选、浮选精矿细菌氧化或焙烧氧化-氰化浸出两种不同回收金的有效途径,并阐述了适合该金矿的选冶工艺。This paper introduces two effective ways of gold recovery, i.e. by adopting processes of flotation and bacterial oxidation or roasting oxidation-cyaniding leaching for flotation concentrate from the superfine impregnation primary gold ore which is an arsenic and carbon -containing rebellious protosulphide and sets forth a metallurgical process flow applicable for this gold ore.

关 键 词：细菌氧化 焙烧氧化 氰化浸出 浸出率
