摘　　要：基于稀土矿日益难选的背景,对中国的稀土资源分布和特点进行概述,继而系统地综述了近年来国内外学者在稀土选矿方面的研究成果,着重对稀土选矿工艺和浮选药剂方面的研究进行梳理和评述。在稀土矿分选工艺方面分别总结了单一选别工艺和联合选别工艺的研究与应用,在浮选药剂方面则重点论述了稀土捕收剂及抑制剂的种类、应用和研究进展。在此基础上,阐明了今后对稀土矿分选工艺和浮选药剂开发研究的重点。Based on the background that rare earth ores are increasingly difficult to separate, the distribution and characteristics of rare earth resources in China are summarized, and then systemati- cally cited the research results aboutits processing home and abroad in recent years. This paper fo- cuses on the research of its mineral processing technology and flotation reagent. The singleandcom- bined benefieiation flows aresummarized. In terms of flotation reagents the species, application and research progress of collectors and inhibitors are introduced. On this basis, the emphasis of separa- tion process and the development of flotation reagents of rare earth minerals are expounded.
