| 英文摘要 | Bioleaching could be a lower energy consumption and environmental friendly technology to recover precious metals from copper mine tailings and reduce its environmental risk. The citric acid is ubiquitous in copper mine tailings and its effects on bioleaching of copper mine tailings are unknown. The purpose of this study was to assess influence of the agents on bioleaching effect and estimating the mechanism. In this work, bioleaching of copper mine tailings using Acidithiobacillus ferrooxidans ATCC 23270 under aerobic conditions was conducted with addition of citric acid of different concentrations. The results from the detection of Cu, Mn, As, total Fe, ferric, ferrous, pH, Eh and cell numbers in leachate during the 30 days showed that the citric acid accelerated the metals leaching. The scanning electron microscope (SEM) images demonstrated the aggregates and tracks of acid attack that could prove the bioleaching results on the other hand and the chemical dissolving played an important role in the bioleaching process. |
