how does coke help in the extraction of metals Science

Carbon is usually used in the form of coke, or carbon monoxide. Not all metallic oxides can be reduced by carbon or carbon monoxide. Thus, in order to extract metal from its ore the method adopted depends on the reactivity of the metal i.e., its position in the metal activity series.
