Bauxite is the primary source for aluminum (Al). Ores in this group include aluminum hydroxides, gibbsite, boehmite and diaspore. It is not just the concentration of aluminum that is important for bauxite mining, but also the identification of penalty elements such as iron oxide that may also make overall compositional analysis more challenging.Web
