Monazite is used today as a source of REEs in both China and India, where Generally, the sands comprises an assemblage of 6/7 minerals such as – Garnet, Ilmenite, Rutile, Zircon, Sillimanite, Leucoxene[ brown Ilmenite] and Monazite. The monazite content, being genetically associated with Ilmenite, varies from 0.03- 0.08 % in Tamil Nadu coast & 0.08- 2.18% in Kerala coast. The name monazite comes from a Greek word, monazein, which means "to be alone". It is an apt name as it is an allusion to the typical crystal habit of primary origin for monazite as isolated individual crystals in phosphatic pegmatites. All commercially useful deposits consist of transported monazite sands liberated by erosion and concentrated by the action of water, which has sluiced away lighter materials and concentrated the heavy (D = 5.0 to 5.2) grains of monazite, together with ilmenite, zircon, garnet, and other dense minerals.
