the Indian iron ore beneficiation process has not yet found much importance compared with those in the rest of the world. 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
Current industrial practice of processing of iron ore fines in India does not involve much beneficiation. However, few plants in India are treating fines during washing, classification, and jigging process [4].
