    LEACHING OF LOW-GRADE COPPER ORES: A CASE

    2017-6-9 · Sulphide copper minerals chalcocite, covellite and chalcopyrite, which are mostly present in sulphide ores of copper, can be leached only in the presence of oxidants, or with the help of bacteria from the genus Acidithiobacillus (formerly Thiobacillus), which are isolated from mine water. They were later identified as Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans. Kinetics of the leaching of the copper sulphide was significantly slower than the leaching of carbonates and oxides of copper, and the mechanism and the stoichiometry of the process were more complex due to the participation of oxidants in them. For the oxidation of sulphides, various oxidizing agents were used, in addition to oxygen from the air and ferric ion was most widely used on an industrial scale. Ferric ion mostly occurs in the landfill itself in the form of Fe2(SO4)3 as the result of decomposition of pyrite. Therefore, pyrite, which is always present in the ore deposits of copper, is an important mineral, as its oxidation supplies leaching
