摘　　要：粉煤灰的综合利用是目前我国煤炭工业的一件大事,而从粉煤灰中提取有价元素是提高粉煤灰综合利用价值的重要途径之一。文章对其回收方法进行了详细的综述,发现虽然在这方面也进行了大量的工作,但大都处于实验研究阶段,实现产业化的不多。因此,加强从粉煤灰中提取有价元素的研究,并有效地实现产业化是每个科学技术工作者的重要任务。The comprehensive utilization of coal fly ash is a crucial event in our country＇s coal industry at present. And extracting valuable elements from coal fly ash is an important way of improving comprehensive utilization of it. After detailed analysis of the recycling method, the result is as follows： although much work has been clone in this aspect, it is still at the experimental research stage and does not achieve much industrialization. Therefore, it is an important task of every researcher to enforce the work of extracting valuable elements from coal fly ash and to bring out industrialization effectively.
