  • The Extraction of IronChemistry LibreTexts

    Removal of carbon: The still impure molten iron is mixed with scrap iron from recycling and oxygen is blown on to the mixture. The oxygen reacts with the remaining impurities to form various oxides. The carbon forms carbon monoxide. Since this is a gas it removes itself from the iron! This carbon monoxide can be cleaned and used as a fuel gas.
