Abstract: In order to give full play to the important role of clay minerals in the preparation of miner‐ al composites，develop green mining and realize the comprehensive utilization of minerals，aiming at the problem of low utilization rate of clay minerals，the properties，advantages and application of clay minerals in various fields are sorted out. This paper expounds the characteristics of high adsorption performance， rich surface hydroxyl groups and unique crystal structure of clay minerals such as kaolin and sepiolite by industry scholars，the high value-added products in the fields of construction，adsorption，energy storage， environmental protection and so on are prepared，and the material utilization is realized，which provides theoretical support and application reference for the high value application and engineering application of clay minerals.

Key words: kaolin, sepiolite, clay minerals, materialization
