Collectively, the rare earths rank as the 22nd most abundant "element" (at the 68th percentile mark). The non- lanthanide rare-earth elements, yttrium and scandium, are 29th and 44th, respectively, in their abundances. Lanthanum and the light lanthanides (cerium through europium) are more abundant than the heavy lanthanides ( gadolinium ...

1. Introduction. Since the development of ion exchange and other extraction methods, rare earth elements (REEs) have been extracted commercially. The first industrial beneficiation from rare earth minerals (REMs) can be traced back to 1893 when thorium was extracted from monazite, and was used in gas lamp mantles [1].REEs are used in …

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 …
