The physical way is low-cost and has little impact on the environment. Firstly, most impurity minerals are sorted out to purify kaolin. 1. Magnetic separation methods. Magnetic separation is the primary physical iron removal method. Iron mineral impurities in kaolin usually have weak magnetic properties and can be removed by magnetic separation.
Conventional beneficiation processes such as flotation, electrostatic and magnetic separation, gravity methods and flocculation–dispersion using chemical reagents to treat the finer iron ore resources often prove to be inefficient, energy-intensive, costly, and environmentally-toxic.
