Abstract

The global demand of rare earth elements (REE) is increasing at present due to their unique magnetic, high electrical and thermal conductance, fluorescent, chemical properties and their uses in hightechnology applications and in the quest for green energy. China, the largest producer of REE, has largely reduced its export since 2010. As a consequence, all the other countries in the world have intensified their search for REE to meet their demands. The present study may lead to enhancing the REE resources of India.

Abstract

Synchysite-(Ce), CeCaF(CO₃)₂, is a member of the rare earth fluorocarbonate group of minerals, one of the important ore minerals of the rare earth elements (REE). The rare earth fluorocarbonates have considerable interest because of their economic importance. Synchysite-(Ce) was first discovered in syenite pegmatites from Narssarssuk, Greenland. It belongs to the parisite family and can be formed by various geological processes such as magmatic, metasomatic and sedimentary origin as well as in hydrothermal ore deposits.
