Pellet feed grinding by HPGR

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. One of the effects of the beneficiation generally is ...
