为了提高铜的浸出率和浸出速率，对中条山的低品位铜矿石进行了细菌浸出研究，对细菌浸出的介质进行了选择，并对细菌浸出的ｐＨ值、接种量和适用的温度等因素进行了条件选择试验．结果表明，细菌浸出在２０－３４．５℃之间均有氧化浸出活性，在最佳条件下，８６ｈ内铜的浸出率可达到约８０％，比硫酸和Ｆｅ３＋联合浸出的浸出率约高５％。
In order to improve the leaching rate and leaching rate of copper, bacterial leaching of low-grade copper ores from Zhongtiaoshan was studied, and the medium of bacterial leaching was selected. The pH of leachate, inoculation amount and applicable temperature Factors were selected condition test. The results showed that the leaching rate of bacteria was about 80% in 86 h under the optimal conditions, and the leaching rate was about 5% higher than that of sulfuric acid and Fe3 + at 20-34.5 ℃. %.
