Seminar on iron ore beneficiation in india - SlideShare

2018年9月17日  In general, the practice adopted by major steel plants in India is to consume medium to high-grade ores (+62% Fe). It is achieved by resorting to selective mining keeping the cut-off up to as high as 58-60% Fe. Therefore, prime objective of beneficiation is to meet the physical standards as required for iron making.
