; 1 Introduction Bauxite resources in China are abundant. However, most bauxite is diasporic bauxite with the typical character of high content of aluminum oxide and silica and the mass ratio of A12O3 to SiO2 of more than 80% bauxite is 4-6[1]. Main gangue minerals in diasporic bauxite are aluminosilicate minerals such as kaolinite, illite and pyrophyllite[2]. In China......
