An overview of the beneficiation of iron ores via reverse

网页2014年3月10日  1. Introduction Iron is one of the most common elements in Earth's crust. The primary industrial types of iron-bearing minerals include oxides and hydroxides and, to a lesser extent, carbonates: magnetite [Fe3 O 4], hematite [Fe2 O 3], goethite [FeO (OH)], limonite [FeO (OH) × nH 2O] and siderite [FeCO3].
