Monazite definition is - a yellow to red or brown mineral that is a phosphate of thorium and various rare earth elements and occurs especially in sand and gravel deposits.

Reactive monazite and robust zircon growth in diatexites and leucogranites from stroll on the boardwalk, swimming in the ocean, or morning yoga on the sand.

Monazite is produced from heavy-mineral concentrates and then separated out by specific gravity, magnetic processes, and other processes. Specimens are sand-grain size particles. Members of the Monazite Group with dominant REE and P: 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 the REE-bearing components' relative abundance. Monazite sand is mostly mined for its rare elements, cerium, lanthanum and thorium content [ 2]. 1. Digestion of ground monazlte sand in 93 per cent sulfuric acid for five hours at 155° -230°C.

Monazite sand is a mineral which has a phosphate bond form containing thorium (Th) and rare earth metals such as yttrium (Y). cerium (Ce). lanthanum (La).

Monazite sand was quickly adopted as the thorium source and became the foundation of the rare-earth industry. In some of Brazil's HBNRAs, monazite sand deposits are abundant on certain black sand beaches. The external radiation levels on these black sand beaches reach as high as 50 μGy h −1 . The minerals that are present in abundance in these coastal regions of Brazil are monazite, rutile, ilmenite, zircon, cassiterite, thorianite, pyrochlore and niobate-tantalite. Monazite is an important mineral resource, it is one of two minerals that are mined for their rare earth content, the other being bastnäsite which is even more important as a source of lanthanides but not as common in sand. It is mined from sand, mostly beach sand. Monazite concentrate from North Carolina, USA. Width of view 3 mm.

The initiative will produce value-added rare earth products from natural monazite sands, a byproduct of heavy mineral sands mined in the southeastern United States. Energy Fuels will process the monazite sands into a mixed rare earth carbonate (RE Carbonate) in Utah for use as feed material for Neo’s value-added separated rare earth production plant in Europe.

Monazite Sand. Monazite is a thorium-bearing mineral that occurs in sand deposits in a number of places around the world. Only a small proportion of the sand in this sample is actually monazite: It is probably somewhat selected compared to normally occurring sand deposits, but not much.
