process of production of iron

Aug 15 2020 The production of iron from its ore involves an oxidationreduction 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 oxides As a result of these impurities iron must be first separated from the gangue and then converted to pure iron
