Reduction process is used for obtaining a metal from its oxide. For example, zinc oxide is reduced to metallic zinc by heating with carbon. ZnO(s) + C(s) → Zn(s) + CO(g) Besides carbon, highly reactive metals like sodium, calcium, aluminium etc. are used as reducing agents. These displace metals of low reactivity from their oxides. For example, Fe2O3(s) + 2Al(s) → 2Fe(l) + Al2O3(s) + Heat Gold is Metal or Nonmetal ? Gold is a metal found in nature in the free state
