Monazite therefore is an extremely important ore mineral. Monazite describes a group of several closely related phosphates with a varying range of several rare earth elements. Due to the similarity and indistinguishable visual differences of the members, a distinction between the Monazite types are rarely designated, with specimens simply labelled as Monazite. 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 unusual age zonation is probably linked to the mineralogical association of monazite and apatite during metamorphic reactions.’. ‘I dutifully explained that the smoky spots were probably the result of natural irradiation Monazite, a phosphate of the rare earths, is the principal mineral from which the cerium earths and thorium are obtained.

Monazite is a primary ore of several rare earth metals most notably thorium, cerium and lanthanum. All these metals have various industrial uses and are considered quite valuable. Thorium is a highly radioactive metal and could be used as a replacement for uranium in nuclear power generation.
By sourcing monazite supplies from these same producers, Medallion seeks to offer a cost-effective waste disposal alternative for mining operations and to obtain REEs at pennies on the dollar. The main use is for an unseparated mixture of La and the lanthanides called Mischmetal (50% Ce, 40% La, 7% Fe, 3% other metals). This is added to steel to improve its strength and workability. It is also used in Mg alloys. Monazite, phosphate mineral, cerium and lanthanum phosphate, (Ce, La)PO 4, that is the major commercial source of cerium. 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. These monazite uses with monocrystalline silicon are used to power polymer batteries that retain the power to function longer.

2016-11-07 · Thorium is a naturally occurring, slightly radioactive element. It is widely distributed in nature with an average concentration of 10.5 ppm Th in the upper earth’s crust. In general, thorium occurs in relatively small number in Th-enriched minerals: thorite, thorianite, monazite, bastnaesite, and thorogummite. However, the main world resources of thorium are coupled with monazite and
