A review of the beneficiation of rare earth element

Feb 01, 2013 Ion-adsorbed clays are a very important source of heavy rare earth elements (up to 60% of REO content in these clays comes from yttrium group elements) with these elements occurring as rare earth element ions (Zhang and Edwards, 2012). Due to their nature, these clays require little to no physical beneficiation, being processed directly using hydrometallurgical methods.
