摘 要：Bioleaching is an environmentally friendly method for extraction of metal from ores.In this study,bioleaching of copper oxide ore by Pseudomonas aeruginosa was investigated.Pseudomonas aeruginosa is a heterotrophic bacterium that can produce various organic acids in an appropriate culture medium,and these acids can operate as leaching agents.The parameters,such as particle size,glucose percentage in the culture medium,bioleaching time,and solid/liquid ratio were optimized.Optimum bioleaching conditions were found as follows:particle size of 150-177 μm,glucose percentage of 6%,bioleaching time of 8 d,and solid/liquid ratio of 1:80.Under these conditions,53% of copper was extracted.
