iron ore beneficiation pdf

Beneficiation is the use of technological methods for the improvement of quality and structure of iron ores so as to render them usable in current smelting operations or to improve their usability. In considering the utilization of beneficiation on low-grade iron ores, it is first necessary to examine the need for such treatment.

BHQ ore Detail beneficiation studies were undertaken on the BHQ iron ore sample of Hospet area to enrich the iron content suitable for pellet making. The sample on an average contains around 38% Fe, 45 % SiO2 and 0.5% Al2O3. The XRD studies reveals that the minerals associated in the sample are magnetite, hematite and quartz.

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 …
