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].

Read The  The study identified the granitoid (or migmatite) basement rock as by far the major contributor of monazite to the Chhatrapur beach sand. The study also reveals  The structure of monazite from a beach sand sample from Kerala shows small structural differences after heat treatments up to 1130 °C, but large P-O distances   The synthesis and certification of CRM of monazite sand by ISO 13528-2008 and ISO 35-2006 have been done. CRM of monazite sand is necessary to support  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).

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.

2019 — *varför berörs inte radioaktivt avfall från andra energikällor så som vindkraft och solceller? Monazite innehåller upp mot 12% Torium och oftast  It is usually found with other rare earth elements and is most often recovered commercially from monazite sand. It was discovered by Swiss chemist Jean  .se/dylan-jungr-every-grain-of-sand-15th-anniversary-edition/691062063012 https://www.wowhd.se/monazite-various-artists/4560267296036 2021-01-19  Monazite- Ce , etc.

Monazite sand is found in large amounts in India and Brazil, and Australia has large deposits as well. It should be noted, however, that the exact amount of thorium resources is not very well known.

More than three thousand tons of monazite sand are decomposed annually in order to obtain the thorium necessary for the manufacture of incandescent gas mantles. Since monazite is primarily a phosphate of the cerium group metals of the rare earths and as the All commercially useful deposits consist of transported monazite sands liberated by erosion and concentrated by the action of water, which has sluiced away lighter materials and concentrated the heavy (D = 5.0 to 5.2) grains of monazite, together with ilmenite, zircon, garnet, and other dense minerals.

Monazite sand is mostly mined for its rare elements, cerium, lanthanum and thorium content [ 2].

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 sand: Monazite sand with a resinous luster from Malaysia. Monazite is produced from heavy-mineral concentrates and then separated out by specific gravity, magnetic processes, and other processes.
