The production of alumina from bauxite by the Bayer process generates a large volume of residue (red mud). This residue contains a percentage of complex zeolitic sodium aluminium silies, formed by the precipitation of silica from the Bayer liquor and are known as the desiliion product or DSP. The presence of DSP in red mud contributes significantly to making the residue highly alkaline ...
