中文摘要：辉铜矿是最具生物冶金工业利用价值的含铜矿物之一,然而,其生物浸出效率仍有较大提升空间.为了更好地揭示辉铜矿的生物浸出过程,对辉铜矿化学-生物溶解机制和浸出动力学相关研究进展进行综述.系统阐述辉铜矿的晶体结构,总结辉铜矿的化学溶解机制、电化学溶解机制和生物溶解机制,讨论辉铜矿的浸出动力学以及不同浸出参数对辉铜矿浸出的影响,总结辉铜矿生物冶金在工业应用中存在的问题.尽管如此,辉铜矿生物浸出的精细过程和浸出机制仍有待进一步研究.未来可采用同步辐射等多种新型研究方法在化学-生物多学科交叉基础上探明次生硫化铜矿的精细氧化溶解机制,为辉铜矿高效环保提铜奠定基础.

外文标题：Advancements on chemical-biological dissolution mechanism and leaching kinetics of chalcocite

外文摘要：Chalcocite is one of the most industrially valuable copper-bearing minerals available for bioleaching.However,the efficiency of chalcocite bioleaching remains unsatisfactory.To better understand the bioleaching process of chalcocite,researches on chemical-biological dissolution mechanisms and leaching kinetics are reviewed.The crystal structure of chalcocite is systematically characterized.The mechanisms for chemical dissolution,electrochemical dissolution,and biological dissolution are summarized and elaborated.The effects of leaching parameters on the leaching kinetics are discussed,and issues in industrial-scale bioleaching are identified.However,the fine leaching process and leaching mechanism of chalcocite still require further study.New research techniques,including synchrotron radiation-based measurements,can be employed to determine the fine mechanism for chalcocite dissolution with interdisciplinary chemistry-biology studies,which may enable efficient extraction of copper from chalcocite in the future.
