粉煤灰预脱硅碱石灰烧结法提取氧化铝OACSTPCD

This is an article in the field of metallurgical engineering.China is short of bauxite resources,which makes the high alumina fly ash a kind of potential bauxite resources.The extraction of alumina oxide from fly ash will be used as a reserve technology,which will make the in-depth development and research constantly pushed forward.The pre-desilication soda lime sintering method of alumina extraction from fly ash has been introduced as the only large-scale and industrialized manufacture technology.It can provide reference information for technology development and the industrialization,and make the national bauxite strategic reserve system safe.
