    Today, nearly all commercial production of alumina is obtained from standard Bayer process using bauxite ores as a raw material. One of the most important criteria for metallurgical-grade bauxites that can be directly fed to the Bayer process is the total silica content of bauxite. Because, reactive silica which tends to dissolve during bauxite leaching causes excessive caustic soda ...
