An overview of the beneficiation of iron ores via

2014-3-10  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 [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.

Characterization and Beneficiation of Iron Ore Tailings

2015-10-20  In the present paper, an attempt has been made to beneficiate iron ore tailings by selective flocculation using guar gum and starch as flocculants along with sodium hexametaphosphate (SHMP) as the dispersant. The mineralogical studies carried out initially indicated the presence of hematite and goethite as major iron bearing mineral phases along with quartz and kaolinite as major gangue minerals.

2013-8-1  Reverse flotation of iron ore is now drawing more attention in iron ore industry as an efficient beneficiation process (Ma et al., 2011, Filippov et al., 2010, Araujo et al., 2005, Houot, 1983). In reverse cationic flotation, silica and silicates are floated after depressing the iron oxide by suitable reagents such as starch, dextrin, and CMC.
