Separation of thorium from uranium ore SpringerLink

2019-12-7  Thorium-230 has many research applications, but there is not a commercial source of this isotope. However, since 230 Th is part of the 238 U decay chain, it can be separated from naturally occurring uranium. In this work, a novel procedure was developed to separate thorium from uranium ore, consisting of leaching, liquid–liquid extraction, precipitations and ion exchange chromatography.

2014-8-8  Research on thorium as an energy source began in 1940 under the direction of Glenn Seaborg at the University of California, Berkeley. Following the discovery of plutonium-239 and its fissile qualities, similar experiments demonstrated that uranium-233 bred from thorium was also fissile. Seaborg viewed uranium-233 as a potential backup to plutonium-239, whose production was one of the

Why Investing in Uranium Thorium? – PGM Capital

2013-11-24  About Thorium: Thorium is a naturally occurring radioactive chemical element with the symbol Th and atomic number 90. 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 ...
