Most metals are obtained from the ground as ores. In order to obtain the pure metal there are 4 different types of reducing processes that can be used. To remember them we'll use BESH
Blast furnacing using Carbon monoxide and Coke (CO is the chemical symbol for Carbon monoxide and the start of Coke).
Electrolysis usually used for Aluminium and extracts the metal using electricity.
Subsituation, Titanium (Ti) is normally extracted by a displacment reaction.
Hydrogen , Tungsten is extracted by reacting it with hydrogen.
B is for bottle which contains the coke.
The bottle in this case is the blast furnace. This technique is used for the M.I.C Metals (Manganese, Iron and Copper). For this example we'll use iron (Fe).
The furnance is filled with a reducing agent called Coke (a type of carbon). Some of which reacts with the oxygen in the furnance:
C + O2 --> CO2
CO2 + C --> 2CO
This carbon dioxide then reacts with some more coke to get Carbon Monoxide which is another reducing agent.
The iron oxide can then either be reduced by the coke or the carbon monoxide to make iron:
2Fe2O3 + 3C --> 4Fe + 3CO2
Fe2O3 + 3CO --> 2Fe + 3CO2
This process release alot of Carbon dioxide…
