The iron in iron ore comes from iron oxides found in deposits such as massive hematite (the most commonly mined), magnetite, titanomagnetite, and pisolitic ironstone. Most major deposits can be found in sedimentary rocks created by chemical reactions between iron and oxygen in fresh and marine waters between one billion and three billion years ago.
