摘　　要：综述了国内外臭氧在湿法冶金领域的研究现状,除了传统的含氰废水处理外,重点介绍臭氧在难冶金属硫化矿浸出及溶液中低价态金属离子氧化沉淀制备金属氧化物粉体方面的研究现状,具体介绍了其在难处理含金资源、方铅矿、黄铜矿、黝铜矿和辉铜矿的浸出,钴氧化物、羟基氧化镍、银氧化物和二氧化锰等粉体制备方面的应用.最后,探讨了臭氧在湿法冶金领域应用中存在的问题和发展方向.The worldwide status of research progress of ozone in the field of hydrometallurgy is reviewed. In addition to the traditional treatment for cyanide-contained wastewater, this paper focuses on the current research situation of the refractory metal sulfide ore leaching and oxidized precipitation of the low valence metal iron from solution for preparation of metal oxide powder. The leaching of refractory gold-bearing resources, galenite, chalcopyrite, tetrahedrite and chalcocite, and the powder preparation of cobalt oxide, nickel oxyhydroxide, silver oxide and manganese dioxide are introduced in detail. Finally, the existing problems and developing direction of ozone used in the field of hydrometallurgy are discussed.
