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.

The BHQ ore was assayed as 38.9wt Fe, 42.5wt SiO2, and 1.0wt.
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 2545 , SiO 2 3060 and Al 2 O 3 15 .Author Hrushikesh Sahoo, Bhagyalaxmi Kar, Swagat S. Rath, D. Srinivas Rao, Bisweswar DasCited by.
Apr 01, 2014 Direct and reverse flotation of banded magnetite quartzite ore is attempted. • Anionic flotation could result 57 Fe only. • Cationic flotation enhanced to 63 Fe with 68.9 iron recovery. • Response surface methodology is applied for optimization of parameters. • Flotation response is strongly dependent on the collector and pH of the slurry.
