【Abstract】 With the increasingly outstanding problems of land and environmental pollution caused by the accumulation of fly ash in China. This paper summarizes the present situation of development and application of fly ash resources. This paper briefly introduces the application of fly ash in large amount of doping,such as building materials,agriculture,mining and environmental protection. Moreover,the application status of fly ash in high value-added field is introduced in detail,such as deep separation of fly ash,extraction of alumina,extraction of rare metals and synthesis of high value-added products. Finally,the paper proposes the existing problems and the development trend of fly ash resource utilization in future.更多还原
