Metal Extraction Equations
  1. Titanium
    1. Reducing Titanium Chloride
      1. TiCl₄ + 4Na > Ti + 4NaCl
        1. Sodium or Magnesium can be used
      2. Titanium Oxide to Titanium Chloride
        1. TiO₂ + 2C + 2Cl₂ > TiCl₄ + 2CO
      3. Tungsten
        1. WO₃ + 3H₂ > W + 3H₂O
          1. It cannot be reduced with Carbon as this would produce brittle Tungsten Carbide
        2. Blast Furnace
          1. C + O₂ > CO₂
            1. CO₂ + C > 2CO
              1. Fe₂O₃ + 3CO > 2Fe + 3CO₂
          2. Sulfides to Oxides (roasting)
            1. ZnS + 1.5O₂ > ZnO+SO₂
              1. SO₂ + H₂O + 1.5O₂ > H₂SO₄
            2. Aluminium
              1. Al₂O₃ > 2Al + 1.5O₂
              2. Other Metals
                1. CuCO₃ > CuO + CO₂
                  1. 2CuO + C > 2Cu + CO₂
                    1. or
                      1. Cu²⁺ + Fe > Cu + Fe²⁺
                        1. Uses scrap iron, this is more enviromentaly friendly
