摘　　要：本文介绍了稀土选矿的发展现状,从其选矿的工艺流程进行了详细概述,综述了稀土选矿常用的磁选-浮选、磁选-重选、重选-浮选、磁选-重选-浮选联合工艺以及部分化学浸出工艺。不同地区矿石类型、结构性质的不同,导致所选择的工艺和药剂制度亦有所不同。分析研究不同类型稀土矿的选矿工艺方法,对稀土选矿技术发展具有一定指导意义。The development status of dressing technology for rare earth is introduced by elaborating on its mineral processing flowsheet.In this paper,it summaries a variety of joint processes such as magnetic separation-flotation, magnetic separation-gravity separation, gravity separation-flotation, magnetic separation-gravity separation-flotation processes and some chemical leaching processes.Different types and structural properties of ores result in different choice of technology and reagent regime.It is of important significance to analyze the separation methods for the development of rare earth mineral processing.
