| 摘 要： | 本文通过对氧化亚铁硫杆菌浸出青海某地区低品位黄铜矿石的试验,探讨了接种量、矿石粒度、矿浆含量对黄铜矿石摇瓶浸出过程的影响。结果表明：在无菌硫酸浸出过程中,黄铜矿可以自发氧化分解,最终浸出率为15.98%;在有菌浸出过程中,氧化亚铁硫杆菌接种量为5/100（mL/mL）时铜浸出率最高可达31.16%。氧化亚铁硫杆菌浸出黄铜矿在接种量为5/100（mL/mL）,矿石粒径为〈104μm,矿浆含量为5/100（mL/mL）时较为适宜。

| Abstract: | In this paper,for the evaluation of the Thiobacillus ferrooxidans bioleaching to the low-grade copper ores from Qinghai province,the effect of inoculation amount on leaching,particle size,and slurry content(m/V) was investigated.It is indicated that the leaching rate of chalcopyrite for copper in sulfuric acid medium was only 15.98%,but for bioleaching it was as high as 31.16% with inoculation amount 5%.The optimal conditions for chalcopyrite bioleaching with Thiobacillus ferrooxidans were pH 2.0,inoculation amount 5%,particle size <104 μm and slurry content(m/V) 5%. |
