I have included FeO or wüstite even so, strictly speaking, it is not an iron ore since is not found in nature (forget some rare exceptions). It is, however, the iron compound that gets reduced in a smelter because it forms from all the other ores put into the smelter before the final reduction step that produces elemental iron takes place.
