2020-6-1 Finally, these heavy minerals can be naturally concentrated in beach sands forming placer deposits. A detailed study on the behavior of uranium and thorium in beach placer sands may help scientists to solve many geological and environmental problems. The concentrations of uranium and thorium and Th/U and Th/K ratios are given in Table 3. Concentrations of U and Th in soil and sand

2020-6-1 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. This area was selected to study geochemical
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.
2018-9-28 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 of total sample dissolution has been set up for its
Zircon crystals isolated from ultramafic materials such as kimberlites (with zircon crystals potentially derived from Earth's mantle) have, for example, the tendency to be typically very low in the actinide elements thorium (Th < 10 ppm) and uranium (U < 30 ppm) and in the REEs (Heaman et al., 1990).
2019-4-21 investigated. After the mineral thorium content separation, the results indicated the possibility of separation efficiency of uranium from sulfuric acid media containing a mixture of both uranium and rare earth group by anionic exchange resin. The elution of uranium was carried out with a

3.04.2.1 Thorium as an Abundantly Available Resource for Nuclear Fuel. Thorium is more abundant than uranium: The content of thorium in the earth’s crust is estimated to be about three to four times larger than that of uranium. Its most common source is the rare earth mineral monazite. Monazite sand is found in large amounts in India and
Zircon crystals isolated from ultramafic materials such as kimberlites (with zircon crystals potentially derived from Earth's mantle) have, for example, the tendency to be typically very low in the actinide elements thorium (Th < 10 ppm) and uranium (U < 30 ppm) and in the REEs (Heaman et al., 1990).
2007-3-8 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]. The impurities are usually included in the zircon lattice.
