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 separation.(PDF) Beneficiation of Rare Earth Minerals,The difficulty in the separation and reduction of the Rare Earths is the defining aspect of their existence. This extends to the very concentration of Rare Earth bearing minerals.Rare earth elements(REE): industrial technology, smelting,,Rare earths: industrial technology; Introduction; As this group has 17 kinds of elements, the applications of rare earth elements are diversified: compounds from chloride 46% purity and 99.9999% of single rare earth oxides.
