    Dec 16, 2010 To identify and establish beneficiation techniques for banded hematite quartzite (BHQ) iron ore, a comprehensive research on BHQ ore treatment was carried out. The BHQ ore was assayed as 38.9wt% Fe, 42.5wt% SiO2, and 1.0wt% Al2O3. In this ore, hematite and quartz are present as the major mineral phases where goethite, martite, and magnetite are present in small amounts. The

    The iron ore associated with dolomitic itabirite use to have high LOI (as carbonate) and CaO, very low amount of silica and alumina where as those associated with BHJ/BHQ contain higher amount of silica and alumina. BHJ/BHQ use to contain silica as high as 45-65 wt%. The ore often contains higher amount of

    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 BHQ iron ore resources are considered as a waste resource in many parts of the world, especially in India. In a situation where the availability of high-grade calibrated iron ore is insufficient, BHQ iron ore could act as an alternative and a potential raw material to many iron and steel industries if appropriately processed

As the grade of iron in the flotation concentrate of BHQ-1 is more than that of BHQ-2, it is concluded that BHQ-1 is more amenable to reverse flotation due to a better
