| Abstract: | A new technology of leaching fine grain disseminated gold concentrate containing arsenic and sulphur was studied in this paper.The obstruction to chemical reaction coming from the solid phase product layer,which consists of metal hydroxide formed during oxidation of sulphide mineral in alkaline media,was eliminated remarkably by grinding of porcelain ballmill.96.8% of gold was extracted during one step leaching in an hour. |
