Thorium processing, preparation of the ore for use in various products.. Thorium (Th) is a dense (11.7 grams per cubic centimetre) silvery metal that is softer than steel. It has a high melting temperature of approximately 1,750 °C (3,180 °F).
Mining Process. Thorium is a relatively abundant element in the Earth's crust. Scientists estimate that the crust contains about 15 parts per million of the element. The thorium in monazite, thorite, or other minerals is first converted to thorium dioxide (ThO2).

Thorium 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 high-quality solid fuel. Additionally, Th is quite inert, making it difficult to chemically process. This is irrelevant for fluid-fueled reactors discussed below.
Thorium Investing. Take a look at the word thorium. What do you see? ... Thermal breeding, as the process is called, requires the reactor to produce more fissile material than it consumes, and it requires a highly specialized type of reactor. ... Though neither company has reported on significant mining of thorium, both are well-positioned to ...
Thorium is more abundant in nature than uranium. It is fertile rather than fissile, and can only be used as a fuel in conjunction with a fissile material such as recycled plutonium. Thorium fuels can breed fissile uranium-233 to be used in various kinds of nuclear reactors.
Has there been any research on what lunar in-situ processes would have to be developed to mine and process thorium to build nuclear thermal rockets on the Moon? ... Mining lunar thorium for building nuclear rockets on the Moon. ... Mining lunar thorium gains you nothing. Thorium is not fissile and cannot be used to fuel a nuclear rocket, power ...
Efficient mining. The extraction process of thorium from the earth's crust is a much safer and efficient mining method than that of uranium. Thorium's ore, monazite, generally contains higher concentrations of thorium than the percentage of uranium found in its respective ore.
Cost of thorium mining is much less than that of uranium because the radiation danger in the process of thorium mining is »100 times less than in the uranium mining. The most important thorium compound commercially is thorium dioxide. It is used in high-temperature ceramics.

Although thorium is widespread in the environment, most people are not exposed to dangerous levels of the metal. However, people who live near thorium-mining areas or facilities that manufacture products with thorium may have increased exposure, especially if their water comes from a private well.
Thorium is also used more efficiently in the reaction process — thorium inputs are almost completely used up during a nuclear reaction, meaning waste is reduced to a minimum. That is especially ...
Jan 01, 2018· Does abandoned Idaho mine hold key to energy independence . Nov 9, 2012 "There's enough Thorium here to power the United States for 500 Ultimately, in 1972, the Thorium mining operation in Idaho was shut down.
Mining thorium is safer and more efficient than mining uranium. Thorium's ore monazite generally contains higher concentrations of thorium than the percentage of uranium found in its respective ore. This makes thorium a more cost efficient and less environmentally damaging fuel source.
