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。
In this paper, Thiobacillus ferrooxidans leaching a region of Qinghai low-grade brass ore experiments to explore the inoculum size, ore size, pulp content of chalcopyrite shake flask leaching process. The results showed that the chalcopyrite could spontaneously oxidize and decompose during the leaching process of aseptic sulfuric acid, and the final leaching rate was 15.98%. When the inoculation amount of Thiobacillus ferrooxidans was 5/100 (mL / mL) Copper leaching rate of up to 31.16%. Thiobacillus ferrooxidans leaching chalcopyrite is more suitable when inoculum size is 5/100 (mL / mL), ore size is <104 μm and pulp content is 5/100 (mL / mL).
