· The definition in Section 11e.(2) is the tailings or wastes produced by the extraction or concentration of uranium or thorium from any ore processed primarily for its source material content. See Uranium Recovery for more information on 11e.(2) byproduct material.
Separation of Uranium and Thorium from R
Uranium Thorium Separation abstract Rare earths play critical roles in the appliions of advanced materials. Recently, the recovery of rare earths from a variety of resources has gained much interest. Radioactive elements of uranium and thorium are usually associated with rare earth deposits. The separation of uranium and thorium from rare
Uranium Supplies: Supply of Uranium
The 2018 Red Book tabulates about 300,000 tU in Sweden and mentions 24,000 tU in Finland at the Sotkamo mine of Terrafame Oy, for which the government granted a permit in 2020 for uranium recovery by heap leaching. Thorium as a nuclear fuel. Today uranium is the only fuel supplied for nuclear reactors.
Canadian Rare Earth and Thorium Recovery Operations the ...
"Canada developed pioneering rare earth solvent extraction methods to recover the rare earths and thorium as byproducts of uranium recovery operations in Elliot Lake, Ontario, and was a major supplier of these key elements from about 1960 until 1990.
Thorium: the wonder fuel that wasn't
· Attempts to recover uranium 233 from its irradiated thorium fuel were described, however, as a "financial disaster." The last serious attempt to use thorium in a commercial reactor was at the Fort St. Vrain plant in Colorado, which closed in 1989 after 10 years and hundreds of equipment failures, leaks, and fuel failures.

The Thorium Molten Salt Reactor – Thorium MSR Foundation
When including uranium extracted from the oceans it becomes an inexhaustible source of energy. But in a molten salt reactor one can also use thorium as a fuel and it is estimated that there is a factor 3 more thorium on earth that uranium. Thorium is easily accessible and at this moment is mostly a byproduct of rareearth mining.
