Bauxite Mining Market Global Industry Analysis 2026

Bauxite is a silt rock, which consists of high aluminum content. It is the primary source of aluminum in the world. Bauxite primarily comprises minerals such as boehmite, gibbsite, hematite, goethite, ilmenite, and anatase. It is usually found near the surface of the terrain; hence, strip mining, a type of surface mining, is carried out.

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
