| Abstract: |
| The synthetic copper sulfide was leached by bacterium. The effects of Fe2 concentration and potential of slurry on copper leaching rate and the role of bacteria in copper leaching were investigated. The results show that the copper leaching rate is over 99% under the conditions including Fe2 concentration of 88 mg/L, potential of slurry of 550 mV and leaching time of 30 days. The indirect action mechanism of bacteria plays a more important role. |
