Bayer process. The global average for the production of bauxite residue per tonne of alumina is between 1 and 1.5 tonnes, though the range is much broader, so it is estimated that some of the 150 million tonnes of bauxite residue is produced annually. This is generated at some 60 active Bayer plants. In addition there are
