common iron ore processing

Iron ores consist of oxygen and iron atoms bonded together into molecules To convert it to metallic iron it must be smelted or sent through a direct reduction process to remove the oxygen Oxygeniron bonds are strong and to remove the iron from the oxygen a stronger elemental bond must be presented to attach to the oxygen Carbon is used because the strength of a carbonoxygen bond is greater than that of the ironoxygen bond at high temperatures Thus the iron ore must be powdered and mixed with coke to be bu
