    What Is Cryolites Purpose In The Extraction Of Alu

    Feb 14 2009Answers The cryolite lowers the melting point of alluminium oxide to 980 The rule is as it is for all impurities they lower the melting point and raise the boiling point so the reduction of the melting point allows the alluminium to melt at lower temperatures making electrolysis work at lower temperatures hence requires lesser energy
