First choice for HPGR technology and service - Kivigrupp

More recently, HPGRs have also been applied in mineral processing plants, largely in iron ore and diamond treatment. In these industries, the application of HPGR ranges from coarse grinding, e.g. the grinding of 65mm (2.5”) size excess pebbles in AG circulation loops, to final grinding of <100μm material to high Blaine.

Iron ore prices have broadly stabilised over the past few days after the battering they took last week. Iranian iron ore prices reflected this and actually held up better than those of some other origins. This shows in the differential to the MBIOI-62 which, after widening quite significantly last week, narrowed this week to $4.59/t.
