Feb 01, 2013 · The principle separation processes employed in the beneficiation of rare earth minerals include gravity separation, magnetic separation, electrostatic separation and froth flotation. These processes will be examined as they have been applied to rare earth minerals. 3.1.
A review of the beneficiation of rare earth element ...
The only REE bearing minerals that have been extracted on a commercial scale are bastnäsite, monazite, and xenotime. These minerals may be beneficiated using gravity, magnetic, electrostatic and flotation separation techniques. Increased demand for the different products manufactured from REE has resulted in a constriction of supply from China, which currently produces 97% of the world’s …
