Screen apertures in the case of closed-circuit operations typically range from 5mm to 6mm in the case of wet screens, and typically 10mm for dry screens. Reported power savings are in the range of 15-25% for hard, competent ores when compared with traditional semi-autogenous grinding (SAG)/ball mill, or stage crushing/ball mill circuits.

A crucial step in mineral processing – and in Minnesota's iron ore processing – is comminution, a process of crushing and grinding. Large rocks must first be crushed and then ground down to tiny particles to expose the valuable or desired minerals so they can be separated from the waste rock. The prevalence of low-grade and complex ores make …
