Abstract: The innocuous treatment and recycling of materials such as spent aluminum electrolytic cell lining and waste cathode can not only solve the serious environmental pollution caused by its stacking, but also realize the reuse of resources, and at the same time meet the national strategic needs of ecological civilization construction and resource security supply. This paper summarizes the research status of the recycling of waste materials in the spent aluminum electrolytic cell, analyzes the application prospects of these waste materials, and provides ideas for the future research of waste materials in spent aluminum electrolytic cells.
