1821 [1]. From an industrial perspective, bauxite is a natural material that can be economically processed to high-purity alumina in the Bayer Process, thus making bauxite the main aluminum ore. Bauxite consists primarily of a mixture of aluminum hydroxides, gibbsite ( -Al 2 O 3.3H 2 O), boehmite ( -Al 2 O 3.H 2
