Abstract

At the present time Bioleaching is one of major areas of research in metal sulfide concentrate. In this paper the bacterial leaching of Sarcheshmeh copper sulfide concentrate with sulfuric acid in the presence of Thiobacillus ferrooxidans (Sarcheshmeh mine (PTCC1647) and DSM583 from Germany) were investigated to increase the recovery of copper.The chemical composition of the concentrate is 30% Cu, 24% Fe and 31% S. The main mineralogical components of the concentrate are chalcopyrite, chalcocite and pyrite. The effect of parameters such as pH, pulp density and additives FeS2 were studied. The results indicated that leaching of the concentrate with sulfuric acid led to increase the recovery of copper in the presence of Thiobacillus ferrooxidan. This effect was more active using the bacteria from the Sarcheshme mine. Finally the results showed that the addition of FeS2 to the concentrate was beneficial in the recovery of the copper.
