Monazite is a primarily reddish-brown phosphate mineral that contains rare-earth elements. Due to variability in composition, monazite is considered a group of minerals. [ 3 ] The most common species of the group is monazite-(Ce) , that is, the cerium-dominant member of the group. [ 4 ]

Monazite is a waxy mineral that is formed through the crystallization of igneous rocks and the metamorphism of clastic sedimentary rocks. [25] This mineral is typically mined in placer deposits, with gold commonly found as a byproduct. [25] The rare earth element neodymium is found in monazite, making it a rare mineral. [25]
The price per kilogram oscillated between US$4,600 and $13,300 in the period from 1959 to 1998 for 99.9% purity, ... Thulium is found in the mineral monazite.
Bastnäsite and the phosphate mineral monazite are the two largest sources of cerium and other rare-earth elements. Bastnäsite was first described by the Swedish chemist Wilhelm Hisinger in 1838. It is named for the Bastnäs mine near Riddarhyttan, Västmanland, Sweden. [3]
Thorium occurs in several minerals including thorite (ThSiO 4), thorianite (ThO 2 + UO 2) and monazite. Thorianite is a rare mineral and may contain up to about 12% thorium oxide. Monazite contains 2.5% thorium, allanite has 0.1 to 2% thorium and zircon can have up to 0.4% thorium. [2] Thorium-containing minerals occur on all continents.
This plant, the first unit of IREL, was made operational way back in 1952 for processing of monazite, whose capacity was subsequently increased by about three times.Rare Earths Division (RED), Udyogamandal, Aluva is located on the banks of Periyar River in Kerala at a distance of 12 km from the port city of Kochi and 15 km from Kochi International Airport.
