Basics of Rare Earth Processing Methods – MSE Supplies LLCJan 31, 2016· Mining REs is relatively simple – but producing individual elements from the ore is tremendously difficult. Rare Earth processing often requires dozens of procedures – each resulting in minute changes in the complex RE stream.
Rare Earth Element Deposits | Geology for InvestorsRare 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.

RARE EARTH ELEMENTS The separation of rareearth elements had been very difficult due to their similar chemical properties. The chemists have succeeded, for the first time, in separating rare earth elements in very small amounts and of modest purity by fractional crystallization. The method, however, was extremely laborious and time consuming.
