Rare Earth Elementsmonazite Beneficiation

A review of the beneficiation of rare earth . Rare earth elements (REEs) comprise the fifteen elements of the lanthanide series as well as yttrium, and may be found in over 250 different minerals.

The processes for rare earth (RE) extraction include the decomposition of RE minerals, and the concurrent or subsequent leaching of the rare earth elements (REEs) from the decomposed minerals. Ore beneficiation concentrate can be decomposed by, for example, acid roasting, caustic cracking, and chlorination.
