Rare Earth Elements Beneficiation

A review of the beneficiation of rare earth element

Feb 01, 2013 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

The rare-earth elements, also called the rare-earth metals or (in context) rare-earth oxides, or the lanthanides (though yttrium and scandium are usually included as rare-earths) are a set of 17 nearly indistinguishable lustrous silvery-white soft heavy metals. Scandium and yttrium are considered rare-earth elements because they tend to occur in the same ore deposits as the lanthanides and
