Abstract: The solid carbon waste generated in aluminum electrolytic cell is toxic and hazardous waste. The treatment technology of waste anode carbon particles and waste cathode carbon blocks has become a research hotspot in recent years. On the basis of research progress at home and abroad, the author adopted corresponding treatment measures to remove the harmful components and recover the valuable components according to the composition of different carbon solid wastes. Based on the understanding of waste anode carbon particles and waste cathode carbon blocks, the main methods for treating carbon solid waste of aluminum electrolytic cells at home and abroad are briefly described, which can be summarized as roasting method, bubbling fluidized bed method, alkali fusion method, vacuum smelting method, flotation, leaching, high temperature method and safe landfill method. The representative treatment processes and their advantages and disadvantages are briefly described, and a summary and prospect are made.
