Bayer Process

The Bayer process is basically used for the extraction of aluminum hydrate from the bauxite ores with the mass ratio of alumina to silica (A/S) above 9. The sinter process is widely used to process the poor-grade diasporic bauxite ores with A/S below 7, in China and Russia, by sintering the bauxite ore with sodium carbonate and limestone to form sodium aluminate and calcium silicate.
