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].

Bauxite ore is first mechanically pulverized and milled to reduce the particle size and then screened. The crushed ore is mixed with the process liquor containing caustic soda and processed in a grinding mill to produce a slurry containing 35–40% solids. Sodium hydroxide is the main chemical used in the process to extract aluminum hydrate ...
