| Abstract: | The mass fraction of alumina in fly ash can be up to 15%-40%, which was a very good resource for preparing alumina. The preparation processes of extracting alumina from fly ash were introduced, which were mainly acid extraction method, alkaline sintering method and （NH4）2SO4 sintering method. The brief comments were made on the process features and shortcomings, and the development trend was also summerized. |
