Adherent anode slimes can cause anode passivation in copper electrorefining and lower the efficiency of copper electrorefining. Declining concentrate grades cause larger impurity levels in anodes, thus creating larger quantities of slimes in the refining process. In order to investigate the characterization methods for adherent anode slimes in copper electrorefining, experiments were conducted for the Boliden Harjavalta Pori refinery material. Methods such as particle size determination, chemical (ICP) analysis, settling rate determination, XRD, SEM-SE, and SEM-BSE analyses were implemented to explore the properties and behavior of these slimes. The results indicate that each method provides valuable insights into the characteristics of adherent anode slimes, facilitating improved strategies for managing their impact in the refining process. Understanding these characteristics is essential for enhancing the efficiency of copper electrorefining and tailoring approaches to address challenges posed by increasing impurity levels.
