In this paper a model is proposed for the removal of Sb by ion exchange from copper refining electrolytes. The correlation factors for the MX-2, UR-3300s and Dualoc C-467 resins were 0.5531, 0.2839 and 0.5455, respectively, and the model's average percentage error was 3.01%. This study addresses the challenges faced during the electrowinning of copper, particularly the contamination by impurities such as arsenic and antimony. Control of these impurities in the electrolyte is critical to improve the quality of the cathode copper produced. The proposed model allows for better understanding and prediction of the ion exchange process efficiency, specifically focusing on the dynamics of antimony removal. Results indicate that different resins exhibit varying capacities for Sb extraction, and the effectiveness of the process can be influenced by the concentration of Sb in the feed solution. The findings suggest that optimizing resin choice and operational parameters can significantly enhance the ion exchange process for antimony extraction, thus contributing to a more efficient copper refining operation.
