摘　　要：黄铜矿生物浸出过程中会生成元素硫及其他含硫中间产物和衍生物,它们对黄铜矿溶解产生钝化或促进作用。研究黄铜矿生物浸出过程的硫形态转化,可以有效了解阻碍或促进黄铜矿生物浸出的关键物质形态以及影响这些形态形成的机制,从而为进一步了解黄铜矿的钝化机制、揭示黄铜矿的溶解机制奠定理论基础。介绍了黄铜矿生物浸出过程产生的含硫中间产物和衍生物及其硫形态转化研究的进展。Elemental sulfur and other sulfur-containing intermediates and derivatives are formed during chalcopyrite bioleaching.The formation of these products can hamper or facilitate the dissolution of chalcopyrite.The study of sulfur speciation transformation during chalcopyrite bioleaching is a useful way to reveal the speciation and formation of the key materials that hamper or enhance the dissolution of chalcopyrite,therefore,to further understand the passivating mechanism of chalcopyrite,and provide theoretical foundation for further understanding of chalcopyrite dissolution mechanism.The progress on research of the characterization of the sulfur species and their transformation in chalcopyrite bioleaching are reviewed.
