silica removal from bauxite by screening
SILICA REMOVAL FROM BAUXITES | Project | FP2 | CORDIS ...
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.

The conventional process of bauxite ore dressing consists on the removal of natural mud through the steps of crushing, semi-autogenous grinding, crumble in trommel, followed by the removal of the fine fraction (-37 µm) by screening or classification in hydrocyclone and thickening [1, 2], though this process does not remove all the reactive silica.

2017-2-1 · However, some bauxites require some form of screening (either wet or dry) to remove the fine grained material to improve the grade and/or handleability. These deposits usually have a beneficiation plant that washes the bauxite and sends the high silica fines (kaolinite and/or quartz) to a tailings dam prior to ship loading the bauxite.
