| Abstract: | Bacterial leaching of copper-bearing pyrite is studied by use of thiobacillus ferrooxidans.Based on results of flask shaking and small reactor stirring experiments,the effects of parti-cle sizes,pulp density,cell concentration, aeration rate and residence time on copper extrac-tion are investigated. The volumetric oxygen transfer coefficients in a batch leaching bioreac-tor are measured and discussed. |

| Keywords: | copper-bearing pyrite biooxidation volumetric oxygen transfer coefficient |
