Most beneficiation plants in India are just washing material to discard liberated silica and alumina as micro fines using various stages of washing. Currently, India is at the border of a phase transformation from high-grade to medium/low-grade ores because of depletion of high-grade iron ore. The low-grade ores are highly contaminated with alumina
