The mineral bastnäsite (or bastnaesite) is one of a family of three carbonate-fluoride minerals, Bastnäsite and the phosphate mineral monazite are the two largest sources of cerium and other rare earth elements. Although a scarce mineral and never in great concentrations, it is widespread, and one of the more common rare-earth carbonates.

Bastnäsite Ore Processing
At Mountain Pass, bastnäsite ore was finely ground, and subjected to flotation to separate the bulk of the bastnäsite from the accompanying barite, calcite, and dolomite. Marketable products include each of the major intermediates of the ore dressing process: flotation concentrate, acid-washed flotation concentrate, calcined acid washed bastnäsite, and finally a cerium concentrate, which was the insoluble residue left after the calcined bastnäsite had been leached with hydrochloric acid. The lanthanides that dissolved as a result of the acid treatment were subjected to solvent extraction, to capture the europium, and purify the other individual components of the ore. A further product included a lanthanide mix, depleted of much of the cerium, and essentially all of samarium and heavier lanthanides. The calcination of bastnäsite had driven off the carbon dioxide content, leaving an oxide-fluoride, in which the cerium content had become oxidized to the less basic quadrivalent state. However, the high temperature of the calcination gave less-reactive oxide, and the use of hydrochloric acid, which can cause reduction of quadrivalent cerium, led to an incomplete separation of cerium and the trivalent lanthanides. By contrast, in China, processing of bastnäsite, after concentration, starts with heating with sulfuric acid.
Bastnäsite Ore Grinding mill Plant
Grinding the bastnäsite ore to the required fineness needs. When the useful minerals of disseminated coarse-grained, the time will be able to ore grinding mill to the required fineness, so full of useful minerals from the basic solution, then the design should use a grinding process. When the useful minerals of disseminated fine-grained, the first mine in the ore grinding mill to the required fineness, it is necessary to design two or more segments grinding process.
