Mining Process: Rare earth elements - Fraimed

Bastnasite, a fluorocarbonate, is the main source of rare earths accounting for around 94% of the world’s rare earth minerals. Laterite clays occur in China and are rich in lanthanides and yttrium. Monazite, a phosphate, once accounted for around 40% of rare earths mines, but now its contribution is minimal.
