【Abstract】 Combined the nature and chemical elements of fly ash,the new ways and application status of value-added utilization in aspects of preparing silica,zeolite,water treatment and recycling the rare metal were reviewed.Currently,fly ash was mainly applied in construction,transportation and other industries.Though it could promote the utilization rapidly in a short time,there were low value-added products,and fly ash did not give full play to the potential value.In the future,to vigorously develop the value-added products of fly ash would become the main direction in the study of utilization technology of fly ash.更多还原
