Several beneficiation techniques have been tried from time to time to reduce the gangue so that the beneficiated products could be effectively used. Most of the iron ore mines in India produce hematite ores and have washing plants to produce lumps as well as fines. In this process, a part of the fine gangue material is removed from the product.

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, …

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, …

The other common silicate mineral in bauxite ore is quartz. Hematite and goethite are the main iron bearing gangue minerals present in bauxite ore. The India deposits are mostly associated with laterite capping occurring as blankets on the plateau and hill ranges of the coastal and peninsular regions.
