4.2 Mining - Thorium Energy Alliance

The most common way that Thorium used to be separated in the west was from placer sands mined for other material such as Titanium Oxide, the companion mineral containing Thorium was mostly Monazite. A placer sand mine is literally the sand placed over time via erosion, wave action from an ancient beach or glaciers in a vein and simply excavated from the deposit.

Thorium fuel cycle — Potential benefits and challenges

2005-7-1  Thorium is 3 to 4 times more abundant than uranium and is widely distributed in nature as an easily exploitable resource in many countries. Unlike natural uranium, which contains ~0.7% ‘fissile’ 235U isotope, natural thorium does not contain any ‘fissile’ material and is made up of the ‘fertile’ 232Th isotope only. Hence, thorium and thorium-based fuel as metal, oxide or

Thorium Investing - Energy and Capital

2014-5-17  The liquid-fluoride thorium reactor (LFTR), a type of molten salt reactor, is being touted by many as the best solution to thorium-powered nuclear energy. In these types of reactors, thorium and uranium fluorides are combined into a salt mixture that’s heated to a molten substance, which is then used to fuel the reactor.

Thorium Reactor - an overview ScienceDirect Topics

Thorium mining is rather unimportant so far. However, thorium reactors are discussed as a promising alternative to the currently used uranium-based systems eliminating the build-up of large amounts of long-lived transuranium elements such as plutonium in the core and expanding the reach of fissile material beyond the known uranium resources.

Uranium and thorium Geoscience Australia

2021-7-2  Uranium and thorium are not stable. They break down in a process called radioactive decay. More than 99% of natural uranium exists in a form (isotope) called uranium-238 while more than 99% of natural thorium exists as thorium-232. These metals decay very slowly eventually to form lead.

Thorium - World Nuclear Association

Thorium is much more abundant in nature than uranium. Thorium can be used as a nuclear fuel through breeding to uranium-233 (U-233). When this thorium fuel cycle is used, much less plutonium and other transuranic elements are produced, compared with uranium fuel cycles. Several thorium-fuelled reactor concepts are under consideration.
