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.
