SILICA REMOVAL FROM BAUXITES Project FP2

The removal of 85% of iron was also remarkable. It has to be noted that when leaching bauxite by means of organic acids, reprecipitation of silica from the solution takes place because of its low equilibrium solubility. An alkaline wash of the solid residues after leaching is required in order to redissolve the precipitated silica.
