A review of the beneficiation of rare earth element
2013-2-1 1. Introduction. The term rare earth elements (REEs) refers to the fifteen metallic elements of the lanthanide series, coupled with the chemically similar ytrrium, and occasionally scandium (Gupta and Krishnamurthy, 1992).These elements are typically split into two sub-groups, the cerium sub-group of “Light” rare earth elements (LREEs) which includes La to Eu

A review of the beneficiation of rare earth element
Highlights Review conducted of RE mineral beneficiation using English and Chinese language sources. Of the 250 known RE minerals only bastnäsite, monazite and xenotime are extracted commercially. Flotation, using fatty acids or hydroxamates, is the primary separation process for RE minerals. Currently, optimal beneficiation processes employ flotation, gravity and magnetic

2014-8-6 A beneficiation process has been successfully developed specifically for this unique combination of minerals. A tailored flotation-only process effectively removes the majority of the gangue minerals and increases the total rare earth grades 6.9 times into 7.6% of the original feed mass at an overall recovery of 52% of the rare earths.
