Iron ore is the basic raw material for iron and steel making. India is among the leading producers of iron ore in the world and produces about 150 million tons per annum (U. S. []).The total reserves of iron ore in India is around 28.5 billion tons, of this hematite ore is considered to be the most important iron ore because of its high grade quality and lumpy nature.

The beneficiation of low-grade iron ores is a key research and development topic in the mineral processing industry. The gradual exhaustion of high-grade iron ore reserves, and rising consumer iron and steel demand globally necessitate efficient low-quality iron ore beneficiation to meet steelmaking quality requirements. This comprehensive review explores …
