A review of reagents applied to rare-earth mineral flotation

Rare-earth mineral (REM) deposits can be broadly classified into four geological environments: carbonates, alkaline/peralkaline igneous rocks, placers and ion adsorption clays. Apart from ion adsorption clay deposits, which require no mineral processing steps, froth flotation is the most applied beneficiation technique.

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 REE-francolite, and a small amount of REEs is hosted in monazite ((Ce,La,Nd,Th)PO 4), xenotime (YPO 4), etc. [3,4].In the wet-process, these REEs are also leached out with the decomposition of phosphate minerals
