The present invention relates to a method for the treatment of a magnesium-containing radioactive material, the method comprises: i) providing a mixture of the radioactive material and water; ii) contacting the mixture with carbon dioxide gas to thereby dissolve at least a portion of magnesium in said radioactive material and form a magnesium-containing solution; iii) passing the solution through an ion exchange unit to recover magnesium ions. Also disclosed is a method for the treatment of a aluminium-containing radioactive material, the method comprises: i) contacting the radioactive material with alkaline solution to dissolve aluminium; ii) separating the dissolved aluminium and alkaline solution from undissolved radioactive material; iii) contacting the aluminium and alkaline solution with carbon dioxide to precipitate aluminium salts. |
