摘　　要：为了有效回收底吹炼铜炉渣,对炉渣中的各种杂质元素分布、底吹炼铜工艺中的元素分布行为规律进行分析。结果表明:在熔炼渣中,Fe_(2)SiO_(4)、ZnFe_(2)O_(4)、CuFe_(2)O_(4)是主要的物相分布,其中Fe_(3)O_(4)占据少量。在吹炼渣中,Ca_(2)Fe_(2)O_(5)、Cu^(2+)1O、PbO、CuFe_(5)O_(8)是主要的物相分布,其中Pb是以氧化物的形式存在,由于Cu的溶解度较小,因此Zn和As的含量较少,无法检测,少量的Cu由于氧气不足以Cu^(2+)1O的形式存在,由此说明基于元素分布行为的底吹炼铜炉渣回收方法能够有效对炉渣杂质元素进行分析和回收,为提高底吹炼铜工艺炉渣回收利用率提供技术参考。In order to effectively recover bottom blown copper smelting slag,the distribution of various impurity elements in the slag and the distribution behavior of elements in the bottom blown copper smelting process were analyzed.The results indicate that Fe_(2)SiO_(4),ZnFe_(2)O_(4),and CuFe_(2)O_(4)are the main phase distributions in the smelting slag,with Fe_(3)O_(4)occupying a small amount.In the smelting slag,Ca_(2)Fe_(2)O_(5),Cu^(2+)1O,PbO,and CuFe_(5)O_(8)are the main phase distributions,among which Pb exists in the form of oxides.Due to the low solubility of Cu,the content of Zn and As is relatively low and cannot be detected.A small amount of Cu exists in the form of Cu^(2+)1O due to insufficient oxygen.This indicates that the copper smelting slag recovery method based on element distribution behavior can effectively analyze and recover impurity elements in the slag,providing technical reference for improving the recovery and utilization rate of copper smelting slag in the smelting process.
