Ideally the required alumina specification should be known before the bauxite is selected and the refinery is designed. Mostly the bauxite is a given, which already determines some of the quality parameters. A refinery is usually designed for a specific bauxite – but over time this bauxite can change as it is a natural material.

ARTICLE: Addressing the Challenge of Bauxite Residue
Bauxite ore contains 30-60% aluminum oxide (Al 2 O 3). In the Bayer process (Figure 2), the bauxite is digested in a pressure vessel along with a sodium hydroxide solution (caustic soda) at an elevated temperature, which dissolves the aluminum oxide converting it into sodium aluminate, leaving insoluble red mud solids as a by-product.
