| Abstract: | The coal gangue was characterized by XRF,XRD,SEM,TG,TPO-MS methods.Effects of activation conditions on the extraction percent of Si,such as rotation rate,mechanochemistry activation time,alkali quantity,with or without grinding aids were examined by XQM2-2L planetary activator.The results indicate that the extraction percent of Si could be increased with the increasing of activation time or the quantity of KOH,or activation with grinding aids. |
