Abstract
Fly ash comprehensive utilization,is in the coal-fired power plant power generation process,the main solid waste produced,in ad-dition to containing Si elements,but also the presence of a larger number of Al substances,is a good source of aluminum extraction.This paper mainly adopts the acid method,alkali method and acid-base joint process,the extraction of alumina from fly ash process to make a generaliza-tion and summary,a systematic study of the advantages and disadvantages of the three kinds of technology,and the future comprehensive utili-zation of fly ash in the extraction of alumina technology gives the idea of the research,to enhance the value of the use of fly ash put forward a reference.关键词
