Mining and processing of iron ore involves crushing and screening. Iron ore is beneficiated by crushing and then separating the iron from the gangue minerals through screening. This is usually so efficient that lower grade ore can be treated especially when the magnetite is quite coarse.
Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, deep purple, to rusty red.
There are many types of iron ore equipment. There are mainly jaw crushers, stone crushers, cone crushers, ball mills, magnetic separators, spiral classifiers, dryers, etc.
According to the various sources of iron as well as certain economic and safety aspects in regards to its extraction is included, we provide you with a suitable iron ore mining equipment. The course we provide information of Iron ore processing includes comprehensive information on the beneficiation of iron ore including comminution, sintering, upgrading, and pelletizing aspects.
Large pieces of iron ore are uniformly sent to the jaw crusher (stone crusher) by the vibrating feeder through the silo for coarse crushing; the coarsely crushed iron ore is screened by the vibrating screen and sent by the belt conveyor Hydraulic cone crusher for fine crushing;
The iron powder of 0-12 mm sieved by the vibrating screen is evenly sent to the ball mill for grinding, and is sieved by the spiral classifier, and the iron powder that does not meet the requirements is sent to the ball mill to continue grinding.
Iron exists in magnetite, hematite, and limonite with weak magnetic separation in part of iron tailings. The gangue minerals are main quartz, calcite, and other minerals without magnetic. Therefore, iron in tailings can be recovered depending on the magnetic differences. Because of the characteristics of iron tailings, if the indexes of magnetic separation are not ideal, fine grinding can be used for monomer dissociation of iron minerals to increase magnetic separation effort. Magnetic separation is simple without extra pollution, which is wildly used in iron ore tailings re-processing at present.
