| Abstract Scope |
There has been decreasing the grade of copper concentrate, leading to an increase in impurities load of copper smelter globally. Among such impurities, lead has a detrimental impact on electrorefining operation causing the passivation of anode. Although reductive smelting of dust to produce lead bullion has been known to be an option of lead bleeding off the copper production circuit, impurities other than lead included in “dirty concentrate” in recent years may suffer the operations of lead smelting and successive refining of the bullion, as well. The present paper will suggest a process from pretreatment of feed to the lead smelter to pyro-refining of bullion to ensure satisfactory quality of bullion while managing impurities other than lead and discuss process factors which are crucial for the process design of the present process. |
