The basic methods of beneficiation for iron ores are usually the same as for nonferrous ores. Of course some difference can be occurred because of the mineralogy and the type of intergrowth.Beneficiation facilities. Crushing. Primary crushers are used as gyratory or jaw crushers. Cone crushers are common for second and third stages of crushing.
