Abstract

Abstract: Red mud is a bulk solid waste generated in the alumina industry,posing a serious threat to the ecological environment.The chemical composition and physical properties of red mud solid waste as well as the correlation with its sources were analyzed.The research progress of red mud in the fields of valuable metal extraction,and the preparation of engineering materials,environmental functional materials and high-value products was systematically reviewed.Research ideas were put forward targeting the separation and purification of critical metal elements,development of low-energy activation technologies,and production of high value-added products,so as to ultimately achieve the multi-stage utilization goal of harmless disposal—resource recovery—high-value utilization of red mud.

Key words: red mud, high-value utilization, metal extraction, ceramic materials, catalytic materials
