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.
WhatsAppعرض المزيد· The liquidfluoride thorium reactor (LFTR), a type of molten salt reactor, is being touted by many as the best solution to thoriumpowered 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.

According to the Atomic Minerals Directorate for Exploration and Research (AMD), a constituent Unit of the Department of Atomic Energy (DAE), India has million tonnes of Monazite which contains 9,63,000 tonnes of Thorium Oxide (ThO2).
WhatsAppعرض المزيدThorium is produced as a byproduct during the processing of the rareearth thorium phosphate mineral monazite, itself a byproduct of processing heavy mineral sands for ilmenite, rutile, zircon, and to a lesser extent cassiterite. The United States imported all of its thorium in 2008, yet the reserve base is about 20 percent of the world total.

WhatsAppعرض المزيدThorium fuel is a bit harder to prepare. Thorium dioxide melts at 550 degrees higher temperatures than traditional Uranium dioxide, so very high temperatures are required to produce highquality solid fuel. Additionally, Th is quite inert, making it difficult to chemically process. This is irrelevant for fluidfueled reactors discussed below.
