Everything You Need to Know About Iron Ore Beneficiation
Iron ore is a mineral substance mined and extracted from the Earth's crust. It is a crucial raw material used for various purposes such as steel production, infrastructural development, energy production, etc. Iron ore typically occurs in the form of rocks and minerals, from which metallic iron can be economically extracted.
Beneficiation of Low Grade Iron Ore: Beneficial to whom?
In India, steel mills are known to use premium iron-ore grade of 62 per cent and above; while ores of lower grade, i.e. FE content 58 and below, are preferred for exports. The committee has recommended penalty for failure to adhere to the mandate too. However, post imposition of export duty, sale of lower grade iron ore has been badly hit.
