Aluminum processing, preparation of the ore for use in various products. In addition to its low density, many of the applications of aluminum and its alloys are based on its high electrical and thermal conductivity, high reflectivity, and resistance to corrosion.
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.
