摘　　要：随着易处理硫化矿资源的日益枯竭,低品位难处理氧化矿资源的开发越来越引起重视。硫化浮选是处理氧化铜矿石最经济有效的方法,硫化的好坏直接影响浮选指标。简述了氧化铜矿石常见的硫化方法、硫化作用以及过量硫化造成抑制的原因,重点介绍了表面硫化机理及其影响因素的研究进展。认为利用学科交叉、先进的分析测试手段和计算机模拟等技术手段进一步研究氧化铜表面硫化及硫化影响因素的微观作用机制是未来重要的研究方向。With the depletion of easily treated sulfide ore resources,more and more attention has been paid to the development of low-grade refractory oxide ore resources.Sulfidization flotation is the most economical and effective way to deal with oxidized copper ore.The quality of sulfidizat ion directly affects the flotation index.In this paper,the common methods of sulfidization of copper oxide ore,the function of sulfidization and the reasons of inhibition caused by excessi ve sulfidization are described.The mechanism of surface sulfidization and the research progress of its influencing factors are mainly introduced.It is considered that it is an important research direction in the future to use interdisciplinary,ad vanced analytical and testing methods,computer simulation and other technical means to further study the micro action mechanism of copper oxide surface sulfidization and its influencing factors.
