Sum of all rare earth's content in analyzed samples was found in the range 234 µg/g to 533 µg/g. Coal fly ash samples, had critical REY content ≥30% (except few samples) and an outlook coefficient ≥0.7 which indicates that some samples can be used as secondary resource for rare earth elements extraction.

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