Extraction of aluminum from fly ash by ammonium sulfate roasting-leaching process was studied. The effects of roasting temperature, roasting time and the molar ratio of ammonium sulfate to Al2O3 in fly ash on the extraction of aluminum from fly ash were investigated. The interaction of various factors on the extraction rate of aluminum from fly ash was discussed by response surface method, and the optimum roasting parameters were determined. The phase and microstructure of fly ash raw materials and calcined products were characterized by X-ray diffractometer (XRD) and scanning electron microscope (SEM). The results show that the main product of fly ash activated by ammonium sulfate is NH4Al(SO4)2, and the surface of the roasted product is corroded. The optimum process parameters of activation roasting of fly ash are as follows:roasting temperature is 438 ℃, roasting time is 63.8 min, molar ratio of ammonium sulfate to Al2O3 in fly ash is 7.31. Under the optimum process conditions, the leaching rate of Al is 95.30%, and the leaching effect is better.

研究了采用硫酸铵焙烧—浸出工艺从粉煤灰中提取铝,考察了焙烧温度、焙烧时间、硫酸铵与粉煤灰中Al2O3物质的量比对粉煤灰提铝的影响,并通过响应曲面法探讨了各因素对粉煤灰提铝率的交互影响规律,确定了最佳焙烧参数。同时,利用X射线衍射仪(XRD)、扫描电子显微镜(SEM)对粉煤灰原料及焙烧产物的物相和微观形貌进行表征。结果表明:粉煤灰硫酸铵活化焙烧后的主要产物为NH4Al(SO42,焙烧产物表面出现了腐蚀现象;粉煤灰活化焙烧最佳工艺参数为焙烧温度438 ℃,焙烧时间63.8 min,硫酸铵与粉煤灰中Al2O3物质的量比为7.31,在该工艺条件下,Al浸出率为95.30%,浸出效果较好

研究了采用硫酸铵焙烧—浸出工艺从粉煤灰中提取铝,考察了焙烧温度、焙烧时间、硫酸铵与粉煤灰中Al2O3物质的量比对粉煤灰提铝的影响,并通过响应曲面法探讨了各因素对粉煤灰提铝率的交互影响规律,确定了最佳焙烧参数。同时,利用X射线衍射仪(XRD)、扫描电子显微镜(SEM)对粉煤灰原料及焙烧产物的物相和微观形貌进行表征。结果表明:粉煤灰硫酸铵活化焙烧后的主要产物为NH4Al(SO42,焙烧产物表面出现了腐蚀现象;粉煤灰活化焙烧最佳工艺参数为焙烧温度438 ℃,焙烧时间63.8 min,硫酸铵与粉煤灰中Al2O3物质的量比为7.31,在该工艺条件下,Al浸出率为95.30%,浸出效果较好

Extraction of aluminum from fly ash by ammonium sulfate roasting-leaching process was studied. The effects of roasting temperature, roasting time and the molar ratio of ammonium sulfate to Al2O3 in fly ash on the extraction of aluminum from fly ash were investigated. The interaction of various factors on the extraction rate of aluminum from fly ash was discussed by response surface method, and the optimum roasting parameters were determined. The phase and microstructure of fly ash raw materials and calcined products were characterized by X-ray diffractometer (XRD) and scanning electron microscope (SEM). The results show that the main product of fly ash activated by ammonium sulfate is NH4Al(SO4)2, and the surface of the roasted product is corroded. The optimum process parameters of activation roasting of fly ash are as follows:roasting temperature is 438 ℃, roasting time is 63.8 min, molar ratio of ammonium sulfate to Al2O3 in fly ash is 7.31. Under the optimum process conditions, the leaching rate of Al is 95.30%, and the leaching effect is better.
