| Abstract: | Fly ash was actived by a method of mechanical grinding,and then some leaching tests were conducted to extract the aluminium oxide from the ash in acid solutions.The structural and micromorphological changes of the ash were analyzed before and after grinding activation.The leaching results indicate that the chemical activities of grass phase aluminium oxide in the ash could be excited by the grinding method.The leaching rate of the aluminium oxide in the ash could increase to 74.5%. |

| Keywords: | fly ash mechanical grinding activation acid leaching aluminium oxide |
