| 英文摘要 | Biooxidation and bioleaching are disposal methods for copper mine tailings to recover metals and to reduce the environmental threat of toxic elements. However, copper mine tailings contain numerous residual common flotation agents such as sodium dodecyl sulphate (SDS) whose effect on biooxidation remains unknown. In the present work, the effects of SDS on biooxidation copper mine tailings by Acidithiobacillus ferrooxidans were investigated on 5 mg/L and 10 mg/L respectively. The results showed that 10 mg/L SDS completely inhibited A. ferrooxidans growth and caused biooxidation loss due to damage to the cell membrane and changes in mineral surface hydrophilicity. Scanning electron microscope (SEM) observations of the surface of copper mine tailings after 30 days of biooxidation clearly show that aggregates suggest a combination of chemical and biological oxidation during biooxidation of copper mine tailings due to the presence of A. ferrooxidans. The results of the study indicated that A. ferrooxidans could recover from treatment with 5 mg/L SDS but Cu dissolution rate did not improve. |
