Effect of Cu2+ ions on bioleaching of marmatite CHEN Song(陈 松), QIN Wen-qing(覃文庆), QIU Guan-zhou(邱冠周) Key Laboratory of Biometallurgy of Ministry of Education, School...; Abstract: The effect of Cu2+ ions on bioleaching of marmatite was investigated......
as Acidthiobacillus ferrooxidans. Because of the high activity of oxidizing ferrous and sulfide mineral, strain GF was used in bioleaching of marmatite. The Zn concentration is 0.273 g/L under the steriled control and 7.30 g/L with adapted GF strain incubated after 29 d in leaching marmatite. The isolated strain GF can be used to leach marmatite in industry application. Key words: acid mine drainage......

strain DX-A in the flask respectively containing pyrite and marmatite for 28 d, the mass concentrations of the Fe2+ and Zn2+ reach to 2.36 g/L and 2.47 g/L, respectively, while those of the controls are only 0.60 g/L and 0.39 g/L. After strain DX-A and A. ferrooxidans ATCC23270 together leached pyrite as well as marmatite, the mass concentrations of Fe2+ and Zn2+ are 2.7% and 10.3% respectively......
