Bauxite actually refers to the industrial use of bauxite, one hydrous soft bauxite or one hydrous hard bauxite as the main mineral composition of the ore collectively. Its application fields include metal and nonmetal.

Bauxite is a good raw material for the production of aluminum metal zui. It is also the main application field of zui, and its consumption accounts for more than 90% of the total production of bauxite in the world.

Bauxite is mainly used as refractory materials, abrasive materials, chemicals and high aluminum cement raw materials. Bauxite is used in a wide range of non-metallic applications despite its small proportion. For example, in terms of chemical products, sulfates, trihydrates and aluminum chloride can be used in papermaking, water purification, ceramics and petroleum refining. Activated alumina can be used as catalyst, catalyst carrier and physical adsorbent for decolorization, dehydration, degasification, deacidification and drying in chemical, oil refining and pharmaceutical industries. The aluminum chloride produced by r-al2o3 can be used for organic synthesis of dyes, rubber, medicine and petroleum. Glass composition of 3% - 5%Al2O3 can improve melting point, viscosity, strength; Grinding material is the main raw material of advanced grinding wheel and polishing powder. Refractory is an indispensable building material in industry.

Aluminium is the second most important metal in the world after steel, with world consumption reaching 3.29kg per person in 1995. Aluminum is widely used in various sectors of the national economy because of its small specific gravity, good thermal conductivity, easy machining and many other excellent properties. Currently, the construction, transportation and packaging sectors are the largest users of zui worldwide, accounting for more than 60 percent of total aluminum consumption. Aluminum is an indispensable raw material for electrical industry, aircraft manufacturing industry, mechanical industry and civil appliances.
