    The method of extraction from ores is strictly dependant on the reactivity of the metal. In fact, some metals like magnesium are too reactive to be reduced by carbon.

    When red by carbon works, it is cheap (but might not yield as much as other methods do).
    When it doesn't, electrolysis can be used at the (very high) cost of melting the ore.
