摘要/Abstract

摘要： 针对某铜冶炼企业在铜阳极泥回收处理过程中出现的效率低、污染大等问题，提出了一种全湿法处理铜阳极泥的工艺，并且采用物质流方法对其工艺过程中的铅、铜、银、金、铂、钯等贵贱金属的行为进行研究.结果表明:在全湿法处理阳极泥工艺中，铅、铜、银、金的分布比较集中，铅、铜对处理工艺影响较小；99%左右的金富集到粗金粉中；粗银粉富集了阳极泥中近99%的银；铂和钯的直收率较低，分布较分散，大部分金属铂和钯存在于铂钯精矿、析铂钯后液和分铅渣中.

关键词: 铜阳极泥, 物质流方法, 贵金属, 贱金属, 直收率

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
