Dissolution and radioactive characterization of resistate zircon sand ...

2018年9月28日  Zircon sand plays an important role in the ceramic industry. The presence of the long-lived radionuclides of uranium and thorium in the zircon sand means this material should be considered as NORM and therefore it is necessary to determine the makeup of the radionuclides present and their activity concentration. In this paper, a simple method

TENORM: Hard Rock Metal Mining US EPA

2023年2月16日  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 material (TENORM) can also be found at zircon processing sites.

Zircon - an overview ScienceDirect Topics

Zircon is a widely occurring mineral, with the chemical formula ZrSiO 4.It has a tetragonal crystal structure (space group = I4 1 /amd, a = 6.607(1) c = 5.982(1)) that is commonly reflected in the habit of zircon crystals (Fig. 1).Pure ZrSiO 4 is colorless, but trace element impurities can give rise to color. Brownish and “hyacinth” colors are common; the latter

Radioactivity of Heavy Mineral Sands as an Indicator of

indicator of coastal sand transport processes. Journal of Coastal Research, 7(1), 189-201. Fort Lauderdale (Florida), ISSN 0749-0208. Heavy mineral-rich beach sands, concentrated by wave and wind action, have been found to contain significant gamma radioactivity, due primarily to trace amounts of uranium and thor-ium found in monazite and zircon.

Occupational exposure to natural radioactivity in a zircon sand

This sand contains varying concentrations of natural radionuclides: mostly U-238 but also Th-232 and U-235, together with their daughters, and therefore may need to be regulated by Directive 96/29/EURATOM. This paper describes the method used to perform the radiological study on a zircon sand milling plant and presents the results obtained.
