Abstract: In view of the characteristics of abundant but difficult to be liberated of monohydrous bauxite ore in China,the application status of the grinding aid in the grinding process of bauxite in China,the structural characteristics of monohydrous bauxite and the research progress of the mechanism of the grinding aid are expounded.It is pointed out that the development of environmental protection,high efficiency,green and non-toxic new grinding AIDS and the study of the influence of grinding AIDS on the subsequent flotation and dissolution of bauxite and its mechanism are the development direction of bauxite grinding AIDS in the future,and provide a reference for the development and utilization of bauxite ore in China.

Key words: Bauxite,Grinding aids,Comminution,Dispersing,Adsorption
