Other uranium minerals found in the state include: carnotite, tyuyamunite, autunite, torbernite, gummite, uranophane, kasolite, and an unidentified mineral which may be dumontit. Monazite is the only thorium mineral of possible economic importance that has been reported.
Thus, this monograph "Heavy minerals of economic importance" is the first nearly complete compendium of the economically important heavy minerals, which will be of interest to persons involved in this subject, such as economic geologists, mineral processing engineers, commodity

Monazite occurs in North Carolina, South Carolina, Idaho, Colorado, Montana, and Florida in the United States, and in Brazil, India, Australia, and South Africa. It is an important source of cerium, thorium, and other rare-earth metals and compounds.
Rare earth element (REE) resources are currently of great interest because of their importance as raw materials for high-technology manufacturing. The REE-phosphates monazite (light REE enriched) and xenotime (heavy REE enriched) resist weathering and can accumulate in placer deposits as part of the heavy mineral assemblage. The Atlantic and Gulf coastal plains of the southeastern United ...
Monazite [(REE)PO 4] is ubiquitous in granitic and many metamorphic rocks, sand beach, and is a primary and hydrothermal mineral in carbonatite.Monazite is found throughout the world in placer deposits, beach sands, and important components of carbonatite related REE deposits, such as Bayan Obo and Mount Weld.
Thorium and uranium extraction from rare earth elements in monazite sulfuric acid liquor through solvent extraction ... in the chemical monazite treatment through a solvent extraction technique.

Monazite (CePO 4) and xenotime (YPO 4) are important hosts for REE and thus can be used to monitor REE mass transfer in various settings. In this investigation, the solubilities of synthetic monazite and xenotime were measured in KCl-H 2O fluids at 800°C and 1.0 GPa, using the piston-cylinder apparatus.
Jul 10, 2016· 1. Location, The geographic location of the South China Sea is strategically important. It links the Indian Ocean to the Pacific and is a critical shipping channel — about half the world's merchant ships pass through it. Keeping the South China Se...
Apr 16, 2017· Fund paucity grounds IREL's mineral exploration plans 9 Jul, 2014, 04.55AM IST. IREL has also not been able to sell any of the radioactive monazite mined in last 10 yrs, as it still awaits green clearances for its long-delayed Orissa Sands Complex.
About 4/5 of the country's phosphate rock (much used in fertilizer) is produced in Florida, making it the state's most important mined product. Oil is the second ranking mined product followed by limestone. Clays to filter petroleum and for pottery are produced along with some quantities of ilmenite, monazite, thorium and zircon. Fishing
Thorium (232 Th) is four times more abundant than uranium in nature and has become a new important source of energy in the future.This is due to the ability of thorium to undergo the bombardment of neutron to produce uranium-233 (233 U).The aim of this study is to investigate the production cost of thorium oxide (ThO 2) resulted from the thorium extraction process.
iii. The sands along the coast of Kerala have large reserves of monazite, which is used for producing nuclear power. iv. Low-lying marshy regions of Gujarat are known for producing common salt. v. Fishing is also an important economic activity of the people living in the coastal areas.
Monazite geochronology is a dating technique to study geological history using the mineral monazite.It is a powerful tool in studying the complex history of metamorphic rocks particularly, as well as igneous, sedimentary and hydrothermal rocks. The dating uses the radioactive processes in monazite as a clock.

Monazite. Monazite is a phosphate mineral [(Ce,La,Nd,Th)PO4], the major commercial source of Ce. Occurring as small heavy crystals in granitic and gneissic rocks and their detritus (called monazite sands), monazite contains up to 27wt% of U and Th oxides.

Cerium occurs in various minerals, but the most important commercial sources are the minerals of the monazite and bastnäsite groups, where it makes up about half of the lanthanide content. Monazite-(Ce) is the most common representative of the monazites, with "-Ce" being the Levinson suffix informing on the dominance of the particular REE ...
The Olympic Dam deposit is unusual in that it contains large amounts of rare earth elements and uranium. An economic method for recovering rare earth elements from these deposits has not yet been found. Many other deposits of this type have been identified around the world, but information on their rare earth elements content is generally lacking.
5 101 geochronology (e.g. Janots et al., 2009) and their economic importance (Williams-Jones et al., 2012; 102 Harlov et al., 2016), little is known about the solubility systematics of two of the most important 103 orthophosphate REE-bearing minerals, monazite (CePO4-) and xenotime (YPO4-) in aqueous fluids of 104 various compositions at high P (> 0.5 GPa) and T (> 300 °C).
Titanium occurs primarily in the minerals anatase, brookite, ilmenite, leucoxene, perovskite, rutile, and sphene. Of these minerals, only ilmenite, leucoxene, and rutile have significant economic importance. As a metal, titanium is well known for corrosion resistance and for its high strength-to-weight ratio.
Unclassified members of the Monazite Group.See also: Monazite-(Ce), Monazite-(La), Monazite-(Nd), Monazite-(Sm), Unnamed (Gd-dominant monazite). The name monazite, without a elemental suffix, was the accepted name for all material in this group, regardless of …
Those rocks usually host economic REE ore deposits, making monazite geochronology important in mining exploration. The simplest monazite zonation showing successive crystallisation of melts is concentric zonation, with new monazite crystallised as rims by rims surrounding the core.
