ABSTRACT:
Magnesium is separated from magnesium slag containing radioactive thorium and its daughters by solubilizing magnesium from magnesium slurry using carbon dioxide and separating magnesium from magnesium slurry containing thorium and its daughters by filtering. The process concentrates the radioactive thorium and its radioactive daughters from the magnesium slag and reduces the volume of the radioactive waste that requires disposal.
