  Selective extraction of thorium from uranium and rare earth …

  2020315 · However, the co-existence of thorium with uranium and rare earth elements in the mineral brings arduous hardness for selective extraction of thorium, mainly due to their comparable chemical and physical properties [18], [19]. Commonly, the conventional approach is the liquid-liquid extraction by functional organic extractant [20], [21], [22].

  Uranium and thorium | Geoscience Australia

  202391 · Uranium and thorium are naturally occurring, radioactive heavy metals with unusual properties. The energy generated by the natural breakdown of radioactive elements is immense and can be used in nuclear reactors. Australia has significant resources of both uranium and thorium within the rocks that make up the Australian continent.
