limonite and siderite iron ore in Nigeria

CHEMICAL AND MINERALOGICAL CHARACTERIZATION

limonite or bog-iron ore (2Fe 2 O 3 3H 2 O), which is brownish; and siderite (FeCO 3), which is pale brown. Hematite and magnetite are by far the most common types of iron ore. Pure magnetite contains 72.4 % Fe, hematite 69.9% Fe, limonite 59.8% Fe and siderite 48.2% Fe but, since these minerals never
