Magnetic separation is widely used. All materials with magnetism in the magnetic field can be treated by magnetic separation, which is the main method to treat iron ore. All lean magnetite ores need to remove gangue minerals such as quartz through weakly magnetic field magnetic separators to improve the iron grade of concentrate. …
Magnetic separation of magnesite and dolomite was carried out by using induced roll magnetic separator. A magnesite concentrate of 1.12% CaO with 46.02% yield was obtained from a feed of 5.73% CaO. The ore mineralogy reveals that dolomite is associated with goethite, whereas, magnesite is associated with hematite and magnetite. ...
