to the surface of kaolin and minor muscovite affecting the firing whiteness of products. The ores were dealt with by using the new combined process of attritioning-classification-bleaching and flotation... illite in the kaolin (Fig.1). The halloysite is of needle-like crystal structure that is made of extremely fine hollow tubes with diameter of 100-400 nm. The halloysite is distributed mainly in less......
. When pH is above 10, tertiary amines are mainly in the form of neutral molecules. There is no electro-static effect between collectors and mineral surface, so the recoveries of kaolinite flotation...J. Cent. South Univ. Technol.
