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