Bauxite in the Bayer process. Today, more than 95% of alumina is produced from bauxite using the Bayer process. Bauxite is the ideal raw material because it contains alumina in a noncombined form and in great quantities (30% to 65%). The Bayer process conditions will vary depending on the type of bauxite that is used.
