Pellet feed grinding by HPGR ScienceDirect

15/03/2015 Pellet feed material generally results from fine grinding to achieve a liberation size roughly between 20 μm and 150 μm. Following this, beneficiation is applied to generate concentrate grades of 65–69% Fe, by gravity separation, magnetic separation or flotation, or combinations thereof.

Iron ore pelletization ScienceDirect

01/01/2015 In addition, more iron ore concentrates are being produced due to the increasing need for beneficiation to upgrade low-grade iron ore resources. 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
