Mar 10, 2014 · Iron is one of the most common elements in Earth's crust. The primary industrial types of ironbearing minerals include oxides and hydroxides and, to a lesser extent, carbonates: magnetite [Fe 3 O 4], hematite [Fe 2 O 3], goethite [FeO(OH)], limonite [FeO(OH) × nH 2 O] and siderite [FeCO 3].The genesis of iron ore deposits is variable, similar to numerous other ore types.
Limonite introduction
Limonite is an ore consisting in a mixture of hydrated iron III oxidehydroxide of varying composition. The generic formula is frequently written as FeO OH nH2O, although this is not entirely accurate as limonite often contains a varying amount of oxide compared to hydroxide.
