The principal economic sources of rare earths are the minerals bastnasite, monazite, and loparite and the lateritic ion-adsorption clays. The rare earths are a relatively abundant group of 17 elements composed of scandium, yttrium, and the lanthanides. The elements range in crustal abundance from cerium, the 25th most abundant element of the 78 common elements in the Earth's
Rare earths extracted from clays do not require further milling, crushing or cracking but purely separation and refining – a genuine rare earth concentrate. Breadth and volume of deposit: A huge deposit (over 300mt of REO bearing clays), it has sufficient resources to supply rare earths.
Xenotime preferentially incorporates heavy rare earth elements (HREEs) while monazite incorporates light rare earth elements (LREEs). This is important because LREEs are much more readily available and therefore a xenotime deposit may be more valuable than a deposit of monazite.

Rare earth elements are not particularly rare in the earth's crust – they have an average concentration of up to 220 ppm which is much higher than far more "common" minerals including copper and zinc. The difficulty is that only rarely are REE's found concentrated enough to form an economic ore deposit.
