the 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 of the ore which make heavy medium separation unsuitable (e.g. …
this is replicated in the fact that though a pellet grade concentrate could be obtained the yield is a mere 27%. 1.2 aim of the study: the aim of this project is to propose methods for utilization of low grade iron ore especially banded hematite jasper (bhj) and slimes.
