Rare earth elements-bearing minerals, once separated, contain as many as 14 individual rare earth elements (lanthanides and yttrium) that must be further separated and refined The complexity of extracting and refining rare earth elements is illustrated by a metallurgical flow sheet for the Mountain Pass mine in California (fig 2)
Rare Earth Minerals Processing There are two major REE ore minerals from which predominantly LREE can be extracted with relative ease: bastnaesite and monazite Bastnaesite, a fluorocarbonate mineral and monazite, a phosphate, contain predominantly either cerium, lanthanum or yttrium
CHINA’S RARE EARTH ORE DEPOSITS AND BENEFICIATION , As shown in Figure 2, after crushing the ore is ground to 90 – 95% passing 0074 mm By LIMS , By the end of 2012, the Bayan Obo rare earth flotation concentrator had been developed into an annual output of 250,000 t of REE concentrates (contained 50% REO) .
The PUG Plant is designed to remove barren rock from the ore and thereby increase the concentration of the rare earth minerals, producing a mineral pre-concentrate The PUG process employs a series of crushing, washing, screening, and magnetic sorting methods to concentrate the rare earth-bearing fines and reduce the associated physical mass
