Iron ore is one of the important raw materials for the production of pig iron and steel in the iron and steel industry. There are many types of iron ore. According to the magnetic properties of the ore, it is mainly divided into strong magnetism and weak magnetism.
Sep 25, 2018 Processes based on the gravity separation technique are extensively being used in iron ore beneficiation because of their low cost, ease of operation, and eco friendly nature. The gravity concentration techniques are based on the differential settling velocities of the different particles constituting the ore.They may be removed in the beneficiation plant by washing, magnetic or gravity separation, before further processing of the ore. The most profitable, selective mining becomes possible by identifying regions of low or high grade ore in the mine. XRD is also used to detect iron bearing mineral impurities that are difficult to process.
