Monazite: A rare-earth phosphate mineral. - Geology

What is Monazite? Monazite is a rare phosphate mineral with a chemical composition of (Ce,La,Nd,Th)(PO 4,SiO 4).It usually occurs in small isolated grains, as an accessory mineral in igneous and metamorphic rocks such as granite, pegmatite, schist, and gneiss.These grains are resistant to weathering and become concentrated in soils and sediments downslope from the host rock.

Finer grained rare earth minerals need to be separated using methods such as froth flotation, which absorb a specific collector on the surface of the rare earth minerals to allow a physical separation. Complex ores may not be suitable for beneficiation and require direct, whole of ore leaching in order to recover the rare earth elements.
