摘要	Aluminum was leached out from coal fly ash by pressure acid-leaching method. The effects of coal fly ash size, sulfuric acid concentration, reaction time and reaction temperature on extraction efficiency of aluminum were investigated comprehensively. The phase and morphology of coal fly ash and solid residues after reaction were analyzed by XRD, SEM and IR. The optimal technological conditions for extracting aluminum from coal fly ash were eventually confirmed that coal fly ash with size of 74 mu m and sulfuric acid with concentration of 50% are mixed in pressure reaction kettle to react for 4 h at 180 degrees C. Under the optimal conditions, the extraction efficiency of aluminum can reach 82.4%.
