摘 要: 黃銅礦生物浸出過程中會生成元素硫及其他含硫中間產(chǎn)物和衍生物，它們對黃銅礦溶解產(chǎn)生鈍化或促進(jìn)作用。研究黃銅礦生物浸出過程的硫形態(tài)轉(zhuǎn)化，可以有效了解阻礙或促進(jìn)黃銅礦生物浸出的關(guān)鍵物質(zhì)形態(tài)以及影響這些形態(tài)形成的機(jī)制，從而為進(jìn)一步了解黃銅礦的鈍化機(jī)制、揭示黃銅礦的溶解機(jī)制奠定理論基礎(chǔ)。介紹了黃銅礦生物浸出過程產(chǎn)生的含硫中間產(chǎn)物和衍生物及其硫形態(tài)轉(zhuǎn)化研究的進(jìn)展。

Abstract: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.
Key words: chalcopyrite; bioleaching; sulfur speciation transformation; passivation; secondary cooper-sulfide minerals
