  • Extraction of Copper and Aluminium – Study Material for IIT JEE

    Aluminium is not directly extracted from bauxite. This is because of the fact that, bauxite is always associated with impurities like ferric oxide and silica. If bauxite is used directly for the extraction of aluminium, the iron and silica present in if would deposit at the hode during its electrolytic reduction. The aluminium thus
