摘　　要：The characteristics of bauxite tailing in China were reviewed,and the current utilization methods and the actuality were discussed.It is found that the bauxite tailing is mainly used for production of building materials and chemical products,and extraction of useful component,etc.Meanwhile,the shortages of these utilization methods were analyzed.In order to enlarge the bauxite tailing application,some new utilization paths were proposed,such as preparing zeolite 4A and corundum-mullite composite materials,which are high value added materials.The utilization ways of bauxite tailing were widened,the utilization ratio of resources and the economic benefit were improved.The characteristics of bauxite tailing in China were reviewed,and the current utilization methods and the actuality were discussed.It is found that the bauxite tailing is mainly used for production of building materials and chemical products,and extraction of useful component,etc.Meanwhile,the shortages of these utilization methods were analyzed.In order to enlarge the bauxite tailing application,some new utilization paths were proposed,such as preparing zeolite 4A and corundum-mullite composite materials,which are high value added materials.The utilization ways of bauxite tailing were widened,the utilization ratio of resources and the economic benefit were improved.
