THE FLOTATION OF MARGINAL GIBBSITIC BAUXITE ORES

ABSTRACT Bauxite ore is the primary mineral resource for the production of aluminum metal and includes gibbsite [Al(OH) 3], diaspore [α-AlO(OH)] and boehmite [γ-AlO(OH)]. Gangue minerals generally include iron oxides (Hematite [Fe 2O 3], Goethite [FeO(OH)]), silicates (quartz [SiO 2]), kaolinite [Al 2Si 2O 5(OH) 4] and others such as rutile/anatase [TiO 2].
