Extraction Process of Aluminium from Bauxite Ore
Aluminum is the most abundant metal in the earth's crust and is a constituent of many minerals. However, the material which is highest in aluminum and most free from objectionable impurities is bauxite which, therefore, is practically the only source of the metal under present processes.. Bauxite is the general name given to the hydrated oxides of aluminum.
