Iron ore, limestone and coke is the ‘’stock’ of the blast furnace. This is fed into the furnace at its top. A variety of processes take place within the blast furnace, as the ‘stock’ slowly moves downwards and temperatures increase.

 
The removal of oxygen through the chemical process called ‘reduction’ is crucial (oxygen combines with carbon monoxide, forming carbon dioxide gas). As the stock travels down the furnace, various impurities and gases are removed until only molten iron and slag are left.
