3 Screening machines for iron ore and coal. The crushing and screening systems for iron ore processing vary widely, depending on whether a magnetite or hematite deposit is being mined. While good quality magnetite is now dry-processed, hematite from deposits below the water line requires wet processing due to sticky quartz and clay contaminations.
