Pellet feed grinding by HPGR ScienceDirect
1. Introduction. 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.Most of the high-grade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO). This involves multistages of crushing and screening to obtain lump (−31.5 + 6.3 mm) and fines (approximately −6.3 mm) products.Comminution and classification technologies of iron ore

Biomass briquette as an alternative reductant for low grade iron ore
Slimes, which are the rejects from the washing plant, constitute the majority of the rejected iron ore resources. The most recent reports of iron ore slime beneficiation include hydrocycloning followed 3.32), reductant to feed ratio (delta value: 2.9) and reductant size (delta value: 2.85). The optimum levels of the four factors areThe reasons for choosing jigging for the iron ore beneficiation over other processes include (i) relatively easy separation, (ii) beneficial trade-off between operating cost and reduced yield relative to dense medium processes, (iii) ability to treat ores requiring cut densities higher than a density of 4.0, and (iv) physical characteristics ofLow grade Iron Ore Beneficiation and the Process of Jigging
