It is well known that there are also some rare earth elements (REEs) which coexist in phosphate rock. Most of them are present in the form of isomorphous substitutions for Ca 2+ as REEfrancolite, and a small amount of REEs is hosted in monazite ((Ce,La,Nd,Th)PO 4), xenotime (YPO 4), etc. [3,4].In the wetprocess, these REEs are also leached out with the decomposition of phosphate minerals and ...

Rareearth element Processing ores | Britannica

Rareearth element Rareearth element Processing ores: All rareearth ores contain less than 10 percent REO and must be upgraded to about 60 percent in order to be processed further. They are first ground to a powder and then separated from the other materials in the ore body by various standard processes that include magnetic and/or electrostatic separation and flotation.
