摘　　要：铅锌资源是我国的战略矿产资源,浮选法是硫化铅锌矿物常用的分离手段。作者通过文献分析,介绍了硫化铅锌矿物晶体结构与可浮性的关系,从浮选电化学理论和量子化学理论方面分析了矿浆环境对铅锌浮选分离的影响,从分子角度总结了药剂与铅锌矿物表面的作用机理,归纳了铅锌分离的浮选技术和药剂在工业生产中的应用。目前,铅锌资源回收难度大、新型药剂缺乏,因此,深度揭示药剂作用机理、开发新型绿色药剂是未来铅锌分离的研究方向之一。Lead and zinc resources are strategic mineral resources in China,and flotation is a common separation method for lead-zinc sulfide minerals.The relationship between the crystal structure and floatability of lead-zinc sulfide minerals was introduced,the influence of pulp environment on lead-zinc minerals flotation separation from the aspects of flotation electrochemical theory and quantum chemistry theory was analyzed,the mechanism of the interaction between reagents and the surface of lead-zinc minerals from the molecular point of view was summarized,and the flotation technology of lead-zinc minerals separation and the application of reagents in production were also summarized.At present,it is difficult to recover lead-zinc minerals resources and there is a lack of novel reagents.Therefore,deeply revealing the mechanism of reagents action and developing new green reagents are one of the research directions of lead-zinc minerals separation in the future.
