    Beneficiation of High Silica Bauxite Ores - SpringerLink

    The more is the silica, higher is the soda consumption which increases the cost of alumina production. Physical beneficiation techniques are employed to reduce the reactive silica content of bauxite. Based on several investigations it has been made possible to remove ~30% of silica with 92% recovery depending on the characteristics of the ore.

    Impurities - The Bauxite Index

    The rule of thumb is that, on a weight basis, any mass of silica that reacts in the refining process will cause an equal loss of caustic soda, and an equal loss of alumina to the red mud in the De-Silication Product (DSP). Thus silica is a key determinant of any bauxite’s economic value. Important impurities and their effects listed opposite.
