The present paper describes the beneficiation of Ba nded Hematite-Quartzite (B HQ) from Meghatuburu mine, India. In general, BHQ ores contain around 30–38% Fe, 45–50% SiO 2 and 1–2% Al 2 O 3
‘Beneficiation of banded hematite quartzite from Meghatuburu Mine, Eastern India
The present paper describes the beneficiation of Banded Hematite-Quartzite (BHQ) from Meghatuburu mine, India. In general, BHQ ores contain around 30–38% Fe, 45–50% SiO2 and 1–2% Al2O3 and hence can hardly be used in steel making.
Jul 10, 2014· For example, the structure of silicates present in certain types of low grade iron ores—banded hematite quartzite (BHQ) and banded hematite jasper (BHJ), plays an important role in attaining mineral liberation which subsequently influences the recovery of hematite by flotation.
Jan 13, 2020· This study investigates upgrading of low-grade banded hematite quartzite iron ore (Fe ~31%). Conventional beneficiation was found to be futile. The susceptibility of iron phases to microwave exposure and their selective absorption assists in the liberation of iron values.
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% SiO 2, and 1.0wt% Al 2 O 3. In this ore, hematite and quartz are present as the major mineral phases where goethite, martite, and magnetite are present in small
Fig. 2: XRD pattern Showing the presence of Hematite and Quartz SEM pattern from hematitic band of Banded Hematite Jasper (Fig.3) shows presence of Acicular hematite with interstitial spaces occupied by quartz. EDS analysis shows a high percentage of Si and complex interlocking of hematite and jasper which made it very difficult for beneficiation.
The present paper describes the beneficiation of Banded Hematite-Quartzite (BHQ) from Meghatuburu mine, India. In general, BHQ ores contain around 30–38% Fe, 45–50% SiO2 and 1–2% 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.
This study investigates upgrading of low-grade banded hematite quartzite iron ore (Fe ~31%). Conventional beneficiation was found to be futile. The susceptibility of iron phases to microwave exposure and their selective absorption assists in the liberation of iron values. Microwave exposure of coarse particles at 540 W for 10 min yielded a concentrate with Fe 56.30% and recovery of 50.68%.

banded iron ore formation (BIF)—banded hematite quartzite (BHQ), banded hematite jasper (BHJ) and banded magnetite quartzite (BMQ)—are yet to be explored due to the fine na-ture of the ore which is difficult to treat by straight-forward selective flocculation means. These low grade BIF ores con-tain 28-40% Fe and 40-55% SiO 2. The minerals

India's Iron ore reserve is around 25,249 million tonnes (MT) apart from Banded Hematite-Quartzite (BHQ) and Banded Hematite Jasper (BHJ). Although India is blessed with large reserves of Iron ore containing average grade around 58% Fe, the performance of blast furnaces has been at lower levels in comparison with the developing countries.

Jul 01, 2019· During conventional mining of hematite ores, there is a significant generation of low grade banded iron ores such as BHQ, BHJ, and BMQ which ends up in unused stockpile at the mine sites due to a lack of suitable beneficiation technology (IBM, 2017, Rath et al., 2014). The iron bands in these ores are of hematite, magnetite and the silica bands
