The element iron (Fe) is one of the most abundant on earth, but it does not occur in nature in useful metallic form. Iron ore is the term applied to a natural ironbearing mineral in which the content of iron is sufficient to be commercially usable. Metallic iron, from which steel is derived, must be extracted from iron ore. By definition, steel is a combination of iron
