Abstract: Shaziling Kaolin is difficult to dress because of high content of iron and very fine particles of iron impurity. By means of such processes as high frequency fine screening, selective dispersing - flocculating, sheeling and high gradient magnetic separating, the Al₂O₃、Fe₂O₃、-2µm contents of kaolin concentrate reach the concentration quality index of second - class kaolin.

Keywords: ceramic raw material, selective dispersing - flocculating, high gradient magnetic separating
