摘　　要：以西部矿业公司的硫化铜矿为研究对象，在模拟青藏高原的低温条件（8～10℃）下对氧化亚铁嗜酸硫杆菌种进行低温驯化培养，得到了细菌活性较好的低温驯化菌．用低温驯化培养菌种和原菌种分别对硫化铜矿进行低温摇瓶浸出90天，结果表明，低温驯化菌所需浸出时间比原菌短，对铜的浸出率分别为53．85％和39．86％．The study was designed to leach chalcopyrite with mesophile acidithiobacillus ferrooxidans which have been domesticated at low temperature （8-10℃）. The results showed that the leaching rate of chalcopyrite for copper by the domesticated acidithiobacillus ferrooxidans at low temperature in 90 days was 53.85%. While the original acidithiobacillus ferrooxidans without domesticated was only 39.86%.
