Bauxite is one of the world s most abundant minerals and is strip-mined in many places. Nearly all is processed into alumina for aluminium production. Bauxite contains iron-bearing clay or red mud, which often leaves stains on the hold paint that can prove difficult to remove. Bauxite is an aluminium ore and is the main source of aluminium.
