About Aluminium - Tomago

About Aluminium. Aluminium is the most plentiful metal in the earth's crust. It is found in the form of aluminium oxide in an ore called bauxite. Alumina and bauxite are the two main raw materials in the aluminium making process. Aluminium is obtained by the electrolysis of alumina which extracts pure aluminium metal from alumina.
