Occurring as small, brown, resinous, rather heavy crystals in granitic and gneissic rocks and their detritus (called monazite sands), monazite frequently contains 10–12 percent thorium dioxide (ThO 2 ) and thus represents a major commercial source of thorium as well. Monazite Mineral Facts: Chemical Formula: (Ce,La,Pr,Nd,Th,Y)PO 4 A phosphate of cerium and the other rare earth metals. Monazite has been identified in Cerium, Lanthanium, Neodymium and Praseodymium rich versions. Cerium dominates in nearly all monazite deposits.
India, Madagascar, and South Africa have large deposits of Scientific facts about the mineral Monazite, including characteristics, industrial uses and occurances.

Cerium dominates in nearly all monazite deposits. It also normally contains some Thorium and Uranium, as well as some silica.

In addition, monazite is found throughout the world in placer deposits, beach sands, and is also a component of the ores of the Bayan Obo deposit (Table 6 and Fig. 20). Monazite is a phosphate mineral containing approximately 70% REE oxides.
Energy Fuels is seeking to secure additional quantities of monazite ores that it can use to further this program and has a goal of processing 15,000 tons or more per year in the future.

Global supplies of rare earth elements have been threatened ever since China imposed export quotas in mid-2010. In the aftermath, increased attention was drawn to potential producers like MolyCorp
Solution (By Examveda Team) Monazite is an important ore for thorium, lanthanum, and cerium. It is often found in placer deposits.
Thorium is a highly radioactive metal and could be used as a replacement for uranium in nuclear power generation. Monazite therefore is an extremely important ore mineral. Monazite Mineral Facts: Chemical Formula: (Ce,La,Pr,Nd,Th,Y)PO 4 A phosphate of cerium and the other rare earth metals. Monazite has been identified in Cerium, Lanthanium, Neodymium and Praseodymium rich versions.

Physical properties of rocks are used to identify the type of rocks and to discover more about them. There are various physical properties of Monzonite like Hardness, Grain Size, Fracture, Streak, Porosity, Luster, Strength etc which defines it. Monazite, a phosphate of the rare earths, is the principal mineral from which the cerium earths and thorium are obtained. Fluviatile monazite placers were mined in the Piedmont province of North and South Carolina from 1887 to 1911, and again intermittently from 1915 to 1917; but the principal sources In recent years have been the beach placers of India and Brazil. 2016-11-07 Monazite concentrate obtained are processed under different condition of time, The Indian Rare Earths Ltd. plant situated at always in Kerala, uses four major stages to attack. 2021-02-02 Chemical Name: Monazite Sand/Powdered Monazite Sand .
