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.

Zircon sand (concentrate) from South Africa. Width of view 12 mm. Zircon is very important mineral to geologists. Small amount of zirconium is replaced with uranium which is a radioactive element. We know the half-life of uranium and can therefore calculate the age of zircon crystals. But this is not all.
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.
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.

Abstract. A solvent extraction process is proposed to recover uranium and thorium from the crystal waste solutions of zirconium oxychloride. The extraction of iron from hydrochloride medium with P350, the extraction of uranium from hydrochloride with N235, and the extraction of thorium from the mixture solutions of nitric acid and the hydrochloric acid with P350 was investigated.
[02:50.56] Uranium-lead dating allowed them to go about it in an entirely different way. [02:55.51] What they did was they looked at the grains of zircon in the sandstone. [03:00.26] Zircon is a material that contains radioactive uranium, which makes it very useful for dating purposes.

Thorium is predicted to be able to replace uranium as nuclear fuel in nuclear reactors, ..... monazite sand; its low reactivity makes it difficult to extract thorium from it.
Air tabling of zircon-rich non-conductor products containing quartz enables most of the fine quartz present to be rejected without a markedloss of zircon. The coarser quartz in the air table feed can be separated from the zircon by screening one or more air table products, the oversize products containing most of the quartz and little...
The uranium content of minerals such as zircon and rutile is a key parameter in the economics of mineral sand production as high uranium contents may . by an ionisation process, essentially the removal of electrons from the lattice atoms.
RECOVERY OF ZIRCONIA FROM ZIRCON SANDS The use of zirconia in many fields has grown enormously. The major and cheapest source of zirconia is zircon sand. Despite this, the decomposition of zircon is not easy to achieve due to its stability. Considering the structure of zircon, which is extensively discussed in the literature [3.
