  • Metal Extraction
    • Reduction of Iron(III) Oxide.
      • Carbon
        • 2Fe2O3 +  3C ----> 4Fe + 3CO2
      • Carbon Monoxide
        • Fe2O3 + 3CO ----> 2Fe + 3CO2
    • Reduction of Manganese(IV) Oxide
      • Carbon
        • MnO2 + C --> Mn + CO2
      • Carbon Monoxide
        • MnO2 + 2CO ---> Mn + 2CO2
    • Reduction of Copper Carbonate
      • Carbom
        • 2CuCO3 + -> 2Cu + 3CO2
      • Heat  until Decomposition the reduce with carbon
        • CuCo3 ---> CuO + CO2
          • 2CuO + C ---> 2Cu + CO2
    • Reduction of Tungsten Oxide
      • Hydrogen
        • WO3 + 3H2 --->  W + 3H2O
    • Electrolysis of Aluminium
      • AL2O3 dissolved in molten cryolite to lower melting point.
        • Anode: 2O2- --> O2 + 4e-
    • Extraction of Titanium
      • 1. Titanium oxide is converted to Titanium Chloride.
        • TiO2  + 2C + 2Cl2 --> TiCl4 + 2C0
      • 2. Titanium Chloride is purified by fractional distillation,
      • 3. Reduction of Titanium Chloride.
        • Sodium reducing agent
          • TiCl4 + 4Na --> Ti + 4NaCl
        • Magnesium reducing agent
          • TiCl4 + 2Mg -> Ti + 2MgCl2
