  • Process for selectively concentrating the radioactivity of thorium containing magnesium slag
    Patent number: 5223181
    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.
