There are many commercially important impurities in bauxites, however of these silica (which may be present in various forms) is the most important. 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 ...
