The thorium-to-uranium ratios in sedimentary rocks range from less than 0.02 to more than 21. Ratios in many oxidized continental deposits are above 7, whereas most marine deposits have ratios much below 7. Thus, the thorium-to-uranium ratio varies with sedimentary processing and depositional environment.

5 Largest Uranium Producers in the World for Investors | INN

Thorium 232, which alone makes up nearly all natural thorium, is the most common isotope of thorium in the nature.This isotope has the longest half-life (1.4 x 10 10 years) of all isotopes with more than 83 protons. In fact, its half-life is considerably longer than the age of earth. Therefore 232 Th belongs to primordial nuclides.. 232 Th decays via alpha decay into 228 Ra .

In 2017 the mine was sold for $20.5 million to a consortium – MP Mine Operations – backed by China's Leshan Shenghe Rare Earth Co, with 10% equity and with JHL Capital Group holding 65%.

THORIUM - THE NEW URANIUM - Futureworld

All the power reactors currently operational in the world make use of solid fuel. It is a combination of molten thorium fluoride and uranium fluoride 21 that will be used in this type of reactor; the molten salt stream will serve both as a fuel and a coolant. The salt circulates and fissioning takes place during the process.
