摘　　要：为了提高永平低品位原生硫化铜矿细菌浸出的效率,通过摇瓶试验,研究了Fe^(3+)对低品位原生硫化铜矿细菌浸出的影响。研究表明:在细菌浸出的初始阶段,添加Fe^(3+)可以提高浸出液的氧化还原电位,但不会提高铜的浸出速度和浸出率,相反会抑制铜的浸出,而且随着添加的初始Fe^(3+)浓度增加,抑制作用进一步加强。The effect of adding the ferric ion on improving the efficiency of the bioleaching of Yongping Copper Mine s low-grade primary copper sulfide ores was investigated through shaking flask experiment.The results show that the addition of Fe^(3+) can raise the redox potential,but not accelerate the leaching speed and rate of cop- per from low-grade primary copper sulfide ores at the initial stage of the bioleaching.On the contrary,it inhibits the leaching of copper.The inhibition increases with increase in the ...
