used on a commercial scale for the extraction of titanium. Metals below Carbon in the Reactivity Series. A metal below carbon in the reactivity series (zinc to silver) may be extracted by heating the metal ore with carbon. During the reaction, the metal in the ore is displaced from its nonmetal anion because carbon is more reactive than the metal.
