Microwave exposure of coarse particles at 540 W for 10 min yielded a …

low-grade iron ores such as banded hematite jasper (BHJ) and banded hematite quartzite (BHQ). According to Indian minerals yearbook (2018), the total resources of iron ore are estimated to be around 33.276 billion tonnes, including both hematite and magnetite. About 79% hematite ore deposit is found only in the eastern part of India [1].

Banded magnetite quartzite (BMQ) ore occurs as separate veins in iron ore mines and recovered while mining the natural hematite ore. In India, such ores are considered as low grade iron ores with Fe content of 25–45%, SiO 2 30–60% and Al 2 O 3 1–5%. No commercial plant has been set up so far to recover the iron values from such …

XRD pattern shows the peaks of hematite, magnetite and quartz in the sample. Liberation studies of different grain size reveal that the good liberation is achieved below 150 micron. A simple flow sheet including classification (2 stages), gravity separation, magnetic separation and flotation is formed for the beneficiation of BHJ ore.

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 ...

Similarly, 79.3% of the quartz particles are found to be liberated, and 10.2% are found in the HGM range. This indicates that in the case of BHQ-2 which has thin quartz bands, hematite is better liberated compared to BHQ-1. This is in contrast to quartz liberation, which was found to be better, in the BHQ-1 sample.

Abstract: To identify and establish beneficiation techniques for banded hematite quartzite (BHQ) iron ore, a comprehensive research on BHQ ore treatment was carried out. The …

These banded ores contain iron bands of hematite or magnetite associated with quartz or jasper as the silica bands. Banded hematite quartzite (BHQ) ore, a significant contributor to India's BIF resources, assays around 30–40% Fe, 40–50% SiO 2, and 0.5–2.5% Al 2 O 3 [4]. It has hematite as the iron phase mineral with quartz, …

The separation of iron oxide from banded hematite jasper (BHJ) assaying 47.8% Fe, 25.6% SiO2 and 2.30%Al2O3 using selective magnetic coating was studied. Characterization studies of the low grade ore indicate that besides hematite and goethite, jasper, a microcrystalline form of quartzite, is the major impurity associated with this ore. …

India Steel Vision 2030 includes the steel production of 300 MTPA which calls for approximately 550 million tons of good-quality iron ore. India possess significant deposits of banded iron ores (BHQ, BHJ and BMQ, B-banded, H-hematite, Q-quartzite, J-jasper, M-magnetite) with iron content ranging 30-45%.

Beneficiation of -2 mm low-grade iron ore tailings (50.7% Fe, 10.8% SiO2 and 4.4% Al2O3) from Western Australia was studied. The sample consisted of hydrohematite, goethite and quartz, with lesser kaolinite and shale.
