摘　　要：对合成硫化铜进行了细菌浸出试验,考察了Fe2+浓度和矿浆电位对铜浸出率的影响,以及细菌在铜浸出过程中的作用。结果表明,在Fe2+浓度88mg/L、矿浆电位大于550mV、浸出30天时铜的浸出率大于99%,细菌绝大部分是以间接作用机理进行浸出的。The synthetic copper sulfide was leached by bacterium. The effects of Fe^2＋ concentration and po-tential 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 Fe^2＋ 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.
