某微细粒浸染型金矿选冶工艺流程的探讨

A Discussion on Metallurgical Process Flow of Superfine Impregnation Gold Ore

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.
