A Case Study on Sustainable Iron Ore Tailing Management ...

2020-5-15  Indian mining industries primarily depend upon high-grade fines mainly because of two factors, one is lack of beneficiation infrastructure and high cost of low-grade fines, the second one is lack of proper tail disposal system. Due to lapses in our policies, miners get better premium by selling high-grade fines over low-grade fines. This restricts the flow of low-grade fines
