    Actually its refining-purification of a metal once it is extracted from the ore but part of the same extraction process
    Example with copper:
    The appartus is set up for electrolysis, a tank containing its salt
    solution (acidified CuSO4), a strip a impure metal is made the
    anode(positive electrode) and strip of pure metal the cathode(negative)
    both dipped into the electrolyte(condusting solution). The metal is
    separated using electricity when the circuit is completed and power is
    turned on.

    Electrolysis is the breakdown of chemical compounds by the passage
    of an electric current, with decomposition occuring at the elctrodes. An
    electrode is a conductor placed in a liquid electrolyte(Liquid that
    conducts electricity) One of the electrodes is negatively charged-the
    cathode and the other is positively charged- the anode. Reduction occurs
    at the cathode and oxidation at the anode.

    Metals above carbon in the reactivity series
    (potassium, sodium, lithium, calcium, magnesium and aluminium) are extracted by electrolysis.
    Extraction from the metal ore involves reduction of the metal,
    and electrons can reduce any metal ion.

    The aluminium ore is bauxite: Al2O3

    Electrolysis of Al2O3:
