The commonly used zircon sand beneficiation process is a composite beneficiation process, including gravity separation, flotation, electric separation, magnetic separation and other different processes. The main purpose is to remove the impurities associated with zircon sand, so that it can be effectively purified. 1. Gravity separation.

Owing to their natural radioactivity, uranium (U) and thorium (Th) play significant roles in environmental sciences for monitoring radiation dose and in geological sciences for understanding sedimentary processes. The Odisha coastal area, in eastern India, is a well-known high background radiation area that is rich in monazites and rutile. …
Zircon. The mineral zircon (zirconium silicate) generally occurs in nature as a crystal. Most of the naturally occurring radioactive material (NORM) found in zircon is uranium and thorium, which is created during the crystallization of the mineral from the molten host rock when it is initially formed.
Zircon sand is a natural mixture consisting of zirconium oxide and silicon oxide. Zircon itself can also be seen as a combination of the two oxides, which form a common crystal lattice (Chap. 2).In small amounts, zircon sand also contains hafnium, aluminum, iron, and titanium oxides, as well as traces of uranium and thorium .

zirconium oxychloride production from zircon sand of Vietnam such as Ha Tinh, Hue, Binh Thuan seaside. Techniques for separation of impurities in ZOC final product such as SiO2, Fe2O3, TiO2, rare earths, uranium, and thorium have also been introduced. Content of uranium and thorium in the final product of ZOC is less than 1 ppm.
It is very difficult to remove uranium and thorium without destroying the structure of the crystal Since zircon is a coproduct from the mining of other minerals, NORM and technologically enhanced naturally occurring radioactive allowed to decay 3~5 days for uranium and 7 weeks for thorium before gamma ray counting by a High Purity …

The nature of the zircon crystal is such that the removal of uranium and thorium is not easily accomplished without destruction of the crystal lattice. 1 . Zircon, along with other minerals of value, for example ilmenite, rutile and monazite, is separated from the complex mineral mix by magnetic and electrostatic separation processes.
The zircon sand concentrator is often divided into two parts: wet treatment and dry treatment. In the wet treatment stage, gangue minerals such as quartz, feldspar and mica are removed by gravity separation equipment such as cone concentrator, spiral concentrator, shaker or jig. The heavy minerals (crude concentrate)obtained are further ...
