Monazite is a reddish-brown phosphate mineral containing rare-earth metals.To be more specific, it represents a group of minerals. The most common species of the group is monazite-(Ce), that is, the cerium-dominant member of the group. It occurs usually in small isolated crystals.It has a hardness of 5.0 to 5.5 on the Mohs scale of mineral hardness and is relatively dense, about 4.6 to 5.7 g/cm 3.

Monazite sand from Brazil was first noticed in sand carried in ship's ballast by Carl Auer von Welsbach in the 1880s. Von Welsbach was looking for thorium for his newly invented incandescent mantles.Monazite sand was quickly adopted as the thorium source and became the foundation of the rare-earth industry.

rare earths and uranium be recovered in a form convenient for further processing. Studies were made in the laboratory and in a pilot plant to determine the optlniura conditions for the digestion of monazlte sand and for the separation of thorium, rare earths, and uranium by fractional neutralization of .
Recovery of scandium, yttrium and lanthanides from zircon sand. This is a process for extracting scandium from zircon ore. It utilizes feeding zircon sand to a fluidized bed chlorinator at about 1000° C. to produce a vaporous (principally zirconium and silicon chlorides) phase and a solid residue and recovering scandium from the solid residue.
The processing sequence for the recovery of gold, ilmenite, and zircon from the Moclips Beach sample is shown in figure 2. This sample contained more ilmenite and zircon per ton of sand than any of the other samples obtained from the sand and gravel plants. Analyses of products and distribution of major constituents are shown in table 9.
Dating - Dating - Importance of zircon in uranium-lead dating: The mineral zircon adds three more fundamental advantages to uranium–lead dating. First, its crystal structure allows a small amount of tetravalent uranium to substitute for zirconium but excludes with great efficiency the incorporation of lead. (It might be said that one begins with an empty box.) Second, zircon, once formed, is ...
This leaves the Russian Baddleyite (Kola Peninsula) and zircon as the only industrial sources of zirconia. The major drawback to zircon use is the large amounts of impurities it is found concentrated with, especially radioactive impurities (Uranium and Thorium) [2-3]. Acid leaching of zircon does not remove these impurities [4-5].
Basics of the fission track method for Uranium determination. Uranium is a common trace constituent of many heavy minerals. Apart from uranium minerals sensu stricto, monazite and zircon are typically the main uranium hosts in mineral sand deposits, containing around 100 to 1000 ppm.
