Abstract
The Bayer process technology is widely used for the industrial production of alumina, however, it is significantly impacted by two important defects: firstly, when using low-grade ore for production of alumina the economics become very challenging, and secondly, the discharge of large volumes of alkaline red mud (bauxite residue) to the environment is highly undesirable. Based on the idea of redesigning the extraction phase of the process, a new method of producing alumina by calcification transformation is proposed in this paper. The characteristics, advantages and disadvantages and economy of calcified carbonization, calcified biomass, calcified potassium alkali and chlorinated alkali solution are compared and analyzed. The feasibility of various calcified transformation red muds are compared, and the progress of laboratory and industrial research on calcification transformation methods are analyzed comprehensively.
