摘　　要：利用已开发的多相多成份系统平衡计算模型，对铜熔炼过程进行了模拟，研究了冰铜品位对伴生元素Ｎｉ、Ｃｏ、Ｓｎ、Ｐｂ、Ｚｎ、Ａｓ、Ｓｂ和Ｂｉ在造硅酸铁炉渣和铁酸钙炉渣的铜熔炼体系中分配行为的影响．结果表明：在生产高品位冰铜时，Ａｓ、Ｓｂ和Ｂｉ的脱除率较低，铁酸钙炉渣对脱除有害杂质Ａｓ和Ｓｂ比硅酸铁炉渣有效得多，Ｎｉ、Ｃｏ、Ｐｂ和Ｚｎ则大量进入这两种渣中，得以脱除．By use of the developed equilibrium calculation model, the distribution behavior of accessory elements in copper smelting was simulated with emphasis on effect of matte grade upon distribution of accessory elements such as Ni, Co, Sn, Pb, Zn, As, Sb and Bi matte, gaseous phase and fayalite slag or ferrite slag during copper smelting. Ferrite slag is shown to be more efficient in removing As and Sb than fayalite slag. Fayalite slag and ferrite slag are equally efficient for the removal of Ni, Co, Pb and Zn from matte. 
