目前在许多国家都进行细菌浸出的研究工作,据称有15家企业进行这样的工作,共中有美国的大企业,如阿纳康达、肯尼柯特、诺安达等公司。对细菌过程的研究结果,大大提高了回收率和浸出速度。如果说过去细菌浸出黄铜矿,用了75天,回收率为30—40%Cu,那么今天在35小时内,回收率就可达80—90%Cu。加拿大在研究细菌浸出铜和其他金属方面也取得成就。特别有意义的是研究表面活性剂对金属细 At present, research on bacterial leaching is carried out in many countries. It is said that there are 15 enterprises that carry out this kind of work, including a large number of U.S. companies such as Anaconda, Kenny Curt, Noanda and others. The results of the bacterial process, greatly improving the recovery and leaching rate. If past bacterium leaching chalcopyrite, 75 days, the recovery rate of 30-40% Cu, so today in 35 hours, the recovery rate of up to 80-90% Cu. Canada has also made significant achievements in studying bacterial leaching of copper and other metals. Of particular interest is the study of surfactant to metal fineness
