Bauxite is heterogeneous mineral containing aluminum hydroxide minerals such as gibbsite, boehmite and disapore. It is a sedimentary rock mixed with kaolinite clay that might have some iron oxide minerals mixed in. Bauxite is used as a source of Aluminum Oxide (Al2O3) which is used in ceramics or as an abrasive (or for abrasion resistance). …
