Kaolin Purification,Gravity Separation,Magnetic Separation
For ferromagnetic minerals such as magnetite and ilmenite or iron filings mixed in the process, it is more effective to use magnetic separation to separate kaolin. For weakly magnetic minerals, there are two main methods: one is to roast first to change the mineral to ferromagnetic iron oxide, and then perform magnetic separation; the other method is to use a high gradient strong magnetic field
