This was mainly achieved by selective mining of high-grade ore, keeping the cut-off to approximately 55% Fe. However, due to growing demand of the iron ore, this is not sustainable, therefore the cut-off grade is now revised by the Indian Bureau of Mines to 45% Fe for hematitic and geothitic ores. In addition to this, stringent environmental ...Web
