What is the process of extraction of aluminum

The production of metallic aluminum requires two steps. First the Bauxite ore has to be converted to a mineral called Alumina (aluminum oxide Al 2 O 3 ) by a method called the Bayer process. In this process the Bauxite ore is treated with hot sodium hydroxide solution (2NaOH + 3H 2 O) which dissolves only the Alumina from the Bauxite.
