what is found in an impure mixture of iron ore

Jul 12 2019 · 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 Thus the impure iron coming from the bottom of
