Pre-desilication Soda Lime Sintering Method of Alumina Extraction from Fly Ash

Abstract

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.
