Anodic Slimes Characteristics And Behaviour In Copper Refining

It is known that the cathode purity and the electrolyte treatment are affected by the solids present in the electrolyte. Anodic slimes properties (e.g., chemical composition, crystalline composition, sedimentation) were studied in copper electrorefining. These properties were modified through anodic composition and current density. In this investigation, we have worked with anode material from the Ventana Smelting, Hernan Videla Lira Smelting (ex - Paipote) of ENAMI (National Mining Company) and El Teniente Smelting of CODELCO-Chile (National Corporation of Copper of Chile). The characterization of the anodic slimes was done as a function of current density and anodic composition.
