Bauxite is best defined as an aluminum ore of varying degrees of purity in which aluminum in the form of aluminum hydroxide or aluminum oxide is the largest single constituent. The impurities are largely iron oxide silica and titania. Bauxite varies greatly in physical appearance depending on its composition and impurities. It ranges in colour from yellowish white to gray or from pink to dark red or brown if high in
