Separation of Thorium from Zirconium Carbide Waste by ...

Separation of thorium from zirconium carbide waste is reported. The waste typically contains zirconium, yttrium, uranium, and thorium, along with other impurities including rare earth elements (REEs), iron, calcium, aluminum, hafnium, and titanium. The first step in the separation was selective leaching of zirconium, uranium, and most other impurities with HNO3–HF, .

Zirconium

The inherent toxicity of zirconium compounds is low. Hafnium is invariably found in zirconium ores, and the separation is difficult. Commercialgrade zirconium contains from 1 to 3% hafnium. Zirconium has a low absorption cross section for neutrons, and is therfore used for nuclear energy appliions, such as for cladding fuel elements.
