Effects Of Impurities In Iron Ore Pellet Plant

Jan 01 2015 Although iron ore concentrates are generally higher in iron grade and contain lower impurities the finer size distribution of concentrates limits their usage in iron ore sintering Therefore pelletizing is needed to produce fired pellets from concentrates as burden materials for blast furnaces and direct reduction processes.
