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 ores for any industrial …

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 …

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].
