Mineral sands contain titanium minerals and zircon and thorium bearing materials These minerals have a wide range of uses Information from the World Nuclear Association the global private sector organization that seeks to promote and provide information

Controlling the temperature in a power plant is extremely important Left alone the nuclear chain reaction would create so many neutrons and release so much energy that the temperature would soar The plant s circulating coolant alone is insufficient to cool the reactor so nuclear plants control the temperature by regulating the flow of

Most widespread minerals containing Thorium This list of minerals containing Thorium is built from the mindat org locality database This is based on the number of localities entered for mineral species and is therefore slanted towards minerals interesting to collectors with less coverage of common rock forming minerals so it does not give an undistorted distribution of Thorium mineral species
