| Abstract Scope |
The Bayer process is the primary technology utilized for alumina production, which imposes stringent requirements on the quality of bauxite. Due to the absence of a reasonable and effective large-scale utilization method, a substantial amount of high-alkali red mud generated from the process can only be stored on-site in storage yards, occupying significant land space and posing grave threats to both the environment and human health. Based on prior research, this paper comprehensively summarizes and scrutinizes the current state of alumina production as well as the management of red mud. Commencing with the phase structure of alumina production, this paper delves into the development of two innovative processes: the calcification-carbonization method and the calcification-transformation method. The aforementioned approaches offer pioneering concepts for promoting sustainable development within the alumina industry. |
