Abstract

During the industrial aluminium refining process, harmful solid waste - Spent Carbon Anode (SCA) is generated due to oxidation and slag loss on the surface of the anode carbon, erosion and scouring of the electrolyte solution and aluminum liquid. Therefore, this study uses a simple and clean flotation method to separate and purify the electrolyte from SCA using one-roughing and three-sweeping flotation process based on the characteristics of SCA. By means of analytical characterization, a high purity and recovered electrolyte is obtained, which can be returned to the electrolytic aluminum plant for secondary use. The harmless treatment and resource utilization of SCA is achieved, and the utilization rate of SCA is improved, which achieves the purpose of treating waste with waste.
