摘　　要：自然界中黄铜矿与金属硫化矿物、金属氧化矿物及一些脉石矿物共伴生。在生物浸出体系中,这些共伴生矿物自身溶解出的离子与黄铜矿之间的原电池效应,以及它们的加入对黄铜矿浸出体系氧化还原电位的影响都会对黄铜矿的浸出效率产生影响。从脉石矿物、金属硫化矿物、金属氧化矿物3个方面综述了共伴生矿物对黄铜矿生物浸出影响的研究现状,旨在为提高黄铜矿浸出效率提供理论支持,并对其他难浸硫化矿的高效选别提供借鉴。Chalcopyrite is always associated with sulfide minerals,oxide minerals and gangue minerals in nature.In bioleaching systems,the ions dissolved from these associated minerals,the galvanic effect,and the influence on the redox potentials of chalcopyrite leaching solution will affect the leaching efficiency of chalcopyrite.This paper reviews the research status of the effects of chalcopyrite co-associated minerals on its bioleaching from gangue minerals,metal sulfide minerals and metal oxide minerals,aiming to provide theoretical support for improving the leaching efficiency of chalcopyrite and provide some inspiration for the efficient separation of other refractory sulfide ores.
