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 dryprocessed, hematite from deposits below the water line requires wet processing due to sticky quartz and clay contaminations.

Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, through to deep purple, rusty red and bright yellow.
