In mineral processing, conventional magnetic separators are equipped with traditional magnetic circuits (magnetic iron yoke with copper coils or iron-clad solenoid) that develop magnetic fields of less than 2 T*. For minerals of low magnetic susceptibility, use of these circuits has many disadvantages. Only a separator with a superconducting magnet can contribute to solving the …
>How to Process Kaolin?
Magnetic separation mainly uses the magnetic difference between gangue mineral and kaolin mineral to remove these colored impurities. For magnetite, ilmenite and other strong magnetic minerals or iron filings mixed in the processing process, using the magnetic separation method to separate kaolin mineral is more effective.
