Apart from the reserves of low grade iron ore, the previous washing methodology adopted in mining industries which had discarded the slimes as well as fines containing Fe value between 45%-55% have added 10-15 Mt every year and have been dumped somewhere as a big heap or in tailing pond. It is required to utilize these lost minerals in main stream
