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.
