Abstract: The low efficiency and serious pollution are the main problems needed to be solved in the process of copper anode slime treatment for a copper smelting enterprise. A process of hydrometallurgical treatment of copper anode slime was proposed. The behaviors of the precious and base metals such as Pb, Cu, Ag, Au, Pt and Pd were studied using the substance flow analyses. The results showed that Pb, Cu, Ag and Au distribute intensively in the process of hydrometallurgical treatment and the effects of Pb and Cu on the hydrometallurgical treatment of copper anode slime are insignificant. Almost 99% Au and 99% Ag are enriched in the crude Au powders and crude Ag powders, respectively. The direct recovery rates of Pt and Pd are low and Pt and Pd distribute dispersedly in the Pt-Pd concentrate, Pt-Pd precipitated solution and Pb leached residue.

Key words: copper anode slime, substance flow analysis, precious metals, base metals, direct recovery rate
