In general, BHQ ores contain around 3038 Fe, 4550 SiO2 and 12 Al2O3 and hence can hardly be used in steel making. However, if they are beneficiated and enriched to around 64 Fe, which is possible only in fine size range, they can be utilized in a pelletization plant. The feed sample assayed 37.52 Fe, 42.23 silica and 0.82 alumina.

MTPA to 7.0 MTPA and setting up of MTPA BHJBHQ Beneficiation Plant and 1.2 MTPA Pellet Plant I Slime Beneficiation Plant. The lease area is 608.0 ha which is in Donimalai reserve forest. Forest clearance has been obtained on 06.02.2009. Out of total lease area of 608.0 ha, mining will be carried out in IBO.O ha at the conceptual period.
3.6. 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 SiO 2 and 0.5 Al 2 O 3. The XRD studies reveals that the minerals associated in the sample are magnetite, hematite and quartz.
Sep 01, 2020 Sep 01, 2020 The conventional beneficiation of this type of siliceous BHQ iron ore resource having low iron content is not advisable. Therefore, pelletization of synthesized magnetite concentrate obtained from the magnetization roasting of BHQ emerged as an alternative energy-saving and ore conserving process that may be scaled up and commercialized for low ...

Feb 08, 2020 Cliffs Tilden plant in Cleveland, USA, is the only iron ore beneficiation plant, where selective flocculation technique, using degraded starch as the flocculant, has been applied to produce pellet grade concentrate from a feed containing around 32 Fe . The plant has a capacity of processing 10 million tons and is in operation since 1975.
Re-beneficiation of iron ore tailings from the conventional beneficiation plants The hematite ore Fe 2 O 3 is always associated with limonite amp goethite ores, which cannot be attracted by high gauss magnetic separators in the conventional beneficiation plants. Such tailings have 30-50 left-over Fe, which is a waste of natural resources.

Iron ore is ferrous group of mineral and is the backbone of industrial development and its demand has drastically increased with the increase of industrial development. Since, the high grade iron oxides are depleting very fast and to cope up with the increased demand of the industry, the low grade iron ore in general has become the eye catching of iron industry and in this context Indian BHQ ore of Karnataka
