the process of making pig iron from iron ore

Another way to createsteelfrompig ironis the Bessemerprocess, which involves the oxidation of the impurities in thepig ironby blowing air through the moltenironin a Bessemer converter.The heat of oxidation raises the temperature and keeps theironmolten. As the air passes through the moltenpig iron, impurities unite with the oxygen to form oxides.
