Using a blast furnace. Iron ore is poured into a blast furnace which is heated to several thousand degrees Celsius, carbon is added to react with the oxygen and form carbon dioxide, other elements such as magnesium are added to react with impurities such as sulphur. Once the purification is complete a layer of all the impurities forms on top which is called slag. Remember, the slag always goes on top.
