Iron is rarely found in its pure form on the surface of the earth; as it tends to get oxidized when it comes in contact with atmospheric oxygen. For this reason, most of its ores are in the form of iron oxides.
Making the world better, one answer at a time. Many ores contain metal oxides. Metal oxides are more stable than metals. Energy is required to break the metal oxygen bond in these metal oxides to release the metal in its elemental form.n refining Iron from its ore you put the iron ore in an oxygen deprived environment. This is done by surrounding the ore with coal so that the Carbon in the coal 'robs' the oxygen off of the Iron to foster its own oxidation. This gives the iron not chance to re-oxidize.
