A review of the beneficiation of rare earth element ...

2013-2-1 · 1. Introduction. The term rare earth elements (REEs) refers to the fifteen metallic elements of the lanthanide series, coupled with the chemically similar ytrrium, and occasionally scandium (Gupta and Krishnamurthy, 1992).These elements are typically split into two sub-groups, the cerium sub-group of “Light” rare earth elements (LREEs) which includes La to Eu and the yttrium sub-group of ...
