Chalcopyrite is the primary copper mineral used for production of copper metal. Today, as a result of rapid industrialization, there has been enormous demand to profitably process the low grade chalcopyrite and "dirty" concentrates through bioleaching. In the current scenario, heap bioleaching is the most advanced and preferred eco-friendly technology for processing of low grade, uneconomic/difficult-to-enrich ores for copper extraction. This paper reviews the current status of chalcopyrite bioleaching. Advanced information with the attempts made for understanding the diversity of bioleaching microorganisms; role of OMICs based research for future applications to industrial sectors and chemical/microbial aspects of chalcopyrite bioleaching is discussed. Additionally, the current progress made to overcome the problems of passivation as seen in chalcopyrite bioleaching systems have been conversed. Furthermore, advances in the designing of heap bioleaching plant along with microbial and environmental factors of importance have been reviewed with conclusions into the future prospects of chalcopyrite bioleaching.
黄铜矿是用于生产金属铜的主要铜矿物。如今，由于快速工业化，通过生物浸出有利可图地处理低品位黄铜矿和“脏”精矿的需求巨大。在当前情况下，堆浸是用于处理低品位、不经济/难富集矿石以提取铜的最先进且首选的环保技术。本文综述了黄铜矿生物浸出的现状。讨论了为了解生物浸出微生物多样性所做的努力的前沿信息；基于组学的研究在未来工业领域应用中的作用以及黄铜矿生物浸出的化学/微生物方面。此外，还讨论了目前为克服黄铜矿生物浸出系统中出现的钝化问题所取得的进展。此外，还综述了堆浸厂设计的进展以及重要的微生物和环境因素，并对黄铜矿生物浸出的未来前景得出了结论。
