Bauxite - Wikipedia

Processing. Usually, bauxite ore is heated in a pressure vessel along with a sodium hydroxide solution at a temperature of 150 to 200 °C. At these temperatures, the aluminium is dissolved as sodium aluminate (the Bayer process ). The aluminium compounds in the bauxite may be present as gibbsite (Al(OH) 3 ),...

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.
