China possesses the largest resource of rare earth elements (REE) in the world and the reserve of REE in China takes up over 40 of the total global reserve. China has dominated the world REE production since 1980s. Bayan Obo REE‐Nb‐Fe deposit situated in Inner Mongolia is the world s largest known REE ore deposit with the reserve of 48 Mt REO and the largest REE production resource.

A review of the beneficiation of rare earth . 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
The invention provides hydrometallurgical processes for the recovery of rare earth values from ore using simple crushing without beneficiation to produce an enriched and purified mixed rare earth concentrate. Ore is crushed to a relatively coarse particle size and then treated with relatively small amounts of acid at a relatively modest
despite the high grade recovery of rare earths from laterite ores by conventional mineral beneficiation processes such as froth flotation density or magnetic separation is difficult due to the
The rare earth concentrate is expected to contain sufficient moisture to prevent the generation of dust and to significantly limit the emanation of thoron. Measurements of airborne dust particle sizes inside the mining pit based on four samples so far indicate an average AMAD of µm with a range of µm.
