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 …

Vertical roller mills (VRM) are commonly used in the processing of iron ore for dry grinding for several reasons: vertical roller mill Energy Efficiency: VRMs are known for their energy efficiency.
