Role of Montmorillonite Kaolinite or Illite in Pyrite Flotation

Kaolinite covered much larger area of pyrite surface than montmorillonite owing to the positive charge occurring at the exposed aluminum oxygen octahedral sheet of kaolinite Although illite has a similar 2 1 structure to montmorillonite it showed little or no effect on pyrite flotation which was attributed to its poor swelling nature
