Abstract:Spent carbon cathodes is a kind of solid waste discharged from electrolytic aluminum production, which is harmful to the environment. However, it also contains a large amount of carbon and fluoride, which has high recycling value. Based on the generation and properties of spent cathodes, the harmless and resource utilization technologies of spent cathodes are studied. In order to provide reference for the green and low-carbon development of aluminum electrolysis industry, the advantages, disadvantages and existing problems of different processing and disposal technologies are compared and analyzed, and the comprehensive utilization technology of spent cathodes is prospected. It is hoping to provide reference to the green development for aluminum electrolysis industry.
