Hematite vs Magnetite: Identifying Key Differences
Magnetite ore is different from other types of iron ores due to its magnetic nature and thus it has to undergo different processing techniques. The main method used after crushing and grinding is the magnetic separation, which takes advantage of the magnetic properties of magnetite to sort it from the non-magnetic waste.
