摘　　要：本文探讨了短床离子交换技术在铜电解液开路中去除金属污染物的应用,并论述了硫酸、砷、锑、铋、铁选择性去除工艺。同时,本文也对菲尔普斯道奇公司的埃尔帕索冶炼厂进行了案例研究,描述了短床除硫酸系统+两段选择性沉淀系统生产碳酸镍副产品的工艺史。This paper discusses the short bed ion exchange technique for the removal of metal contaminants from electrolyte bleed streams. Processes for the selective removal of sulfuric acid, arsenic, antimony, bismuth, and iron will be discussed. A case sludy outlining the performance history of a short bed system for sulfuric acid removal followed by a two stage selective precipitation system producing a nickel carbonate by-product at the Phelps Dodge Mining Company El Paso operation will be presented.
