Monazite is an important mineral resource, it is one of two minerals that are mined for their rare earth content, the other being bastnäsite which is even more important as a source of lanthanides but not as common in sand. It is mined from sand, mostly beach sand. Monazite sand is found in large amounts in India and Brazil, and Australia has large deposits as well. It should be noted, however, that the exact amount of thorium resources is not very well known. Monazite is a rare phosphate mineral with a chemical composition of (Ce,La,Nd,Th) (PO4,SiO4).
