Separation of thorium from uranium ore | SpringerLink

Thorium-230, historically known as ionium, is part of the 238 U decay chain (see Fig. 1).There are many research areas today where this isotope is relevant. It is an essential component of uranium–thorium dating which uses disequilibria between the parent isotope 238 U and its daughter 230 Th to date carbonate materials [].This dating …

Thorium | SpringerLink

The name thorium was derived from Thor, Scandinavian god of war. Interest in the metal and its oxide lagged until about 1884. The interest in thorium for nuclear energy application is increased owing to its abundance in the Earth's crust 0.0012% thorium as compared to 0.0004% uranium. Thorium is a major potential source for increasing the ...

Under this condition, over 90% of thorium precipitated out while a small portion of uranium (i.e., 28.7%) and REEs (i.e., 16.3%) co-precipitated with thorium. As indicated in the study of Zhu et al. (2015), the precipitation pH range of thorium is 2.5–5.5, which is consistent with the findings presented in this work.

What is Uranium? | IAEA

There are three natural isotopes of uranium — uranium-234 (U-234), uranium-235 (U-235) and uranium-238 (U-238). U-238 is the most common one, accounting for around 99 per cent of natural uranium found on earth. Most nuclear reactors use fuels containing U-235, however, natural uranium typically contains only 0.72 per …
