Abstract: As the largest alumina producer in the world, China produces a large amount of red mud that has a serious impact on the environment. For many years, China has attached great importance to the treatment of red mud, focusing on the sustainable development of resources and the environment, taking the use of red mud as a means to achieve the secondary purpose of red mud utilization. Researches on the comprehensive utilization technology of red mud in multiple fields and disciplines were carried out. This paper systematically elaborated the physical and chemical properties of red mud and its comprehensive application in environmental management such as sewage treatment, soil remediation, and waste gas treatment, and prospected the future application of red mud in environmental treatment.
