"This international recognition of our work demonstrates that we are on the right track to make Alunorte a global reference for bauxite residue re-use, consolidating a leading position in the industry.

Bauxite: The principal ore of aluminum.

Other materials could be used instead of bauxite for alumina production. Clay minerals, alunite, anorthosite, power plant ash, and oil shale could be used to produce alumina but at higher costs, using different processes. Silicon carbide and synthetic corundum are sometimes used in place of bauxite-based abrasives.

Bauxite Wikipedia

Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium.Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH) 3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe 2 O 3), the aluminium clay mineral kaolinite (Al 2 Si 2 O 5 (OH)) and small
