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.
The rate of ejection of alpharecoil thorium234 into solution from the surface of zircon sand gives an alpharecoil range of 550 angstroms. The alpharecoil thorium234 atoms ejected into the groundwater may supply excess uranium234. In pelagic sediments, ejected alpharecoil thorium234 may contr .
So Radkowsky wrapped clusters of "seeds" fuel rods made of uranium and zirconium in much larger "blankets" of rods made of thorium oxide pellets. The unique reaction that followed, he believed, would result in real improvements over the standard alluranium nuclear fuel.

Remove Thorium And Uranium From Zircon Sand Zirconium and Hafnium USGS Zirconium and hafnium are contained in zircon at a ratio of about 50 to 1 mixture of thorium and cerium and zirconia was produced from zircon sand at plants in. .
Zircon always contains an amount of hafnium, with the HfO 2 /ZrO 2 ratio varying. The amount is usually minute, but certain zircons from Norway contain up to 24% of HfO zircon occurs mainly in pegmatites. Zoned crystals of members of the zircon–hafnon series from Mozambique were described by Correia Neves and colleagues in 1974; these crystals ranged .

Zircon sands contain a significant concen tration of natural radioactivity because thorium and uranium may substitute zirconium in the zircon crystal lattice. The concentration of radioactivity in zircon lies typically within the ranges Bq g 1 and 1e5 Bq g 1 for 232Th and 238U, respectively (NRPB, 1993).

· Silica (SiO2) is present in the trace amounts, as well as small amounts of uranium and thorium. Due to the alpha decay of thorium and uranium, monazite contains a significant amount of helium, which can be extracted by heating. Monazite is an important ore for thorium, lanthanum, and cerium. It is often found in placer deposits.
