Over 300 minerals contain iron but five minerals are the primary sources of iron ore. They are (i) magnetite (Fe3O4), (ii) hematite (Fe2O3), (iii) goethite (Fe2O3.H2O), (iv) siderite (FeCO3), and (v) pyrite (FeS2). The first three are of major importance because of their occurrence in large economically minable deposits.
