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.

The first step in processing iron ore is to crush it into smaller pieces. This is typically done using a jaw crusher or a cone crusher. Jaw crusher use two fixed jaws to crush the ore, while cone crusher use a rotating cone to crush the ore. Screening. Once the ore has been crushed, it is then screened to separate it into different sizes.
