摘　　要：综述了硫化铜矿强化浸出的研究进展,针对铜的强化浸出过程,介绍了多种可能的强化浸出的方法,其中包括氯介质浸出、生物浸出以及添加辅助剂对硫化矿浸出过程的影响。重点阐述了生物强化浸出黄铜矿的研究。指出采用添加活性炭强化生物浸出黄铜矿能够克服浸出过程中存在的钝化现象,是解决黄铜矿浸出速度缓慢最有发展前景的方法。The research progress of intensified leaching of copper sulfide ore was summarized. Variety of possible ways to enhance the leaching of copper sulfide ore were proposed, including chlorine medium leaching, bioleaching and effect of adding auxiliary agents on the process of leaching of copper sulphide ore . The research of bioleaching of the copper sulfide ore was focused on. It is showed that adding activated earbon to intensify the bio-leaching of chalcopyrite can eliminate passivation existed in leaching process, and it is an effective method to solve the prob- lems of low speed of chalcopyrite leaching.
