| 摘 要： | 通过摇瓶试验研究矿石粒度和矿浆浓度对原生硫化铜矿石中细菌浸出的影响,并初步探讨了浸矿过程中细菌的氧化活性及其对浸矿的影响。研究结果表明:在原生硫化铜矿石细菌浸出过程中,有利于铜浸出的矿石粒度和矿浆浓度分别是5 mm和20%~25%;溶液中三价铁含量过高或产生的铁沉淀都会直接影响细菌的氧化活性和浸矿效果。

| Abstract: | The effect of ore size and slurry density on the bioleaching of chalcopyrite ore in shake flask and the oxidation activity of bacteria and its effect on leaching ore are studied.The results show that the beneficial conditions of ore size and slurry density on leaching copper are 5 mm and 20%～25% respectively in the course of bioleaching chalcopyrite ore.The high ferric concentration or the producted precipitation of iron directly affects the oxidation activity of bacteria and its effect on leaching. |
