Welcome to the Web Page of Dr. P. S. RanawatBauxite is a mixture of the minerals gibbsite (Al 2 O 3 3H 2 O) boehmite (alpha monohydrate, Al 2 O 3 H 2 O) and Diaspora (beta monohydrate, Al 2 O 3 H 2 O). It is a unique mineral in the sense that, by and large, this is the only mineral from which aluminum is extracted economically.
