Iron ore analysis

Iron ore. Iron is the fourth most abundant element in the Earth's crust, but economic concentrations are dominated by comparatively rare iron oxide forms; magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (FeOH), limonite (FeO(OH)nH 2 O) and siderite (FeCO 3).The mineralogy of iron ore impacts its commercial value and how it is processed.
