Thorium Extraction Methods UC Homepages

Originally, thorium extraction was a process that was high in energy and waste, using large amounts of heat and solvent. Modern science is working to produce thorium more efficiently. In this paper, several common thorium extraction processes are discussed. Separation of U and Th from Rare Earths by Precipitation This method uses differences in solubility of rare earth

Uranium-233 can be recovered and purified from neutron-irradiated thorium reactor fuels through the thorium extraction, or Thorex, process, which employs tributyl phosphate extraction chemistry. Irradiated fuel, containing either thorium metal or oxide, is dissolved in nitric acid containing a small amount of fluoride ion. Uranium-233 and thorium are coextracted into a

The liquid effluent from solvent extraction contains radioactive thorium Th-231 and Th-234. This invention uses an ion exchange process to remove and concentrate the thorium. The process is designed so that the thorium remains on the ion exchange column until it decays to uranium and protactinium. These decay products are subsequently replaced by additional thorium.
