iron ore reduction

  • Iron Production Chemistry LibreTexts

    The production of iron from its ore involves an oxidation reduction reaction carried out in a blast furnace Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue The iron found in iron ores are found in the form of iron oxid
