| 英文摘要 | Copper mine tailings are harmful to environment because of generating acid mine drainage (AMD). Bioleaching is not only the cause of AMD but also can be regarded as an appropriate disposal of tailings if the toxic elements were oxidized by bacteria and then dissolved in the treatment facilities before discharging into the tailings ponds. The residual floatation agents, such as oxalic acid, are ubiquitous in copper mine tailings and the information of their effects on bioleaching is few. Acidithiobacillus ferrooxidans was used in bioleaching tests with oxalic acid at 200 mg/L and 500 mg/L respectively. The results in determination of Cu, Mn, As, Fe, pH, Eh and cell numbers in leachate during the 30 days indicated that oxalic acid enhanced the metals leaching effects. The morphology of surface on copper mine tailings was observed by scanning electron microscope after the bioleaching. The results show the aggregates and tracks of acid leaching could prove the evidence of bioleaching enhancement. |
