Abstract A large amount of coal gangue is accumulated in the process of coal mining and coal washing, which leads to the waste of land resources and environmental pollution. The synthesis of zeolite from coal gangue is one of the main ways of resource utilization. This paper introduces the preparation methods and mechanisms of coal gangue based zeolite at home and abroad in recent years, as well as the influencing factors in the preparation process. The application progress of coal gangue based zeolite in environmental protection such as water treatment, harmful gas removal and soil remediation is reviewed. At the same time, the future development trend is analyzed and prospected. It is proposed that the exploration of environmentally friendly and low-cost preparation methods, and the use of coal gangue-based zeolite for heavy metal contaminated soil remediation are the focus of future research. The application of coal gangue-based zeolite not only meets the needs of environmental protection, but also achieves the dual effects of coal gangue treatment.

Key words： coal gangue zeolite preparation method process mechanism environmental
