摘 要: 富氧底吹煉銅是一種典型的現(xiàn)代強化煉銅工藝。基于已建立的富氧底吹銅熔煉多相平衡模型，采集了國內(nèi)某底吹煉銅廠實際生產(chǎn)數(shù)據(jù)對其進行驗證，利用驗證后模型對銅富氧底吹強化熔煉過程進行模擬計算，研究入爐物料成分(Cu、Fe、S)和工藝參數(shù)(銅锍品位、富氧濃度、氧礦比)變化對伴生元素Pb、Zn分配行為的影響。結(jié)果表明：提高入爐物料中Cu含量或降低Fe、S含量，適當提高銅锍品位、富氧濃度和氧礦比，有利于Pb、Zn伴生元素向爐渣中定向分離；為提高Pb、Zn脫除率，建議調(diào)控入爐物料中Cu、Fe、S含量分別為25%~26%、16%~19%、27%~28.5%，控制銅锍品位、富氧濃度、氧礦比分別為72%~73.5%、80%~81%、166~168 m3/t。

Abstract:The oxygen-enriched bottom blowing copper smelting is a typical modern intensified copper smelting process. The established multi-phase equilibrium model of oxygen-enriched bottom blowing copper smelting was verified with industrial production data. The verified model was used to calculate the influence of the concentrate composition (Cu, Fe, S) and process parameters (copper matte grade, oxygen-enriched concentration, oxygen-ore ratio) on the distribution behavior of minor elements. The results show that, increasing the content of Cu or reducing the content of Fe and S in the concentrate, and appropriately increasing the copper matte grade, oxygen-enriched concentration and oxygen-ore ratio are beneficial to Pb and Zn into the slag. In order to improve the removal rate of Pb and Zn, it is recommended to adjust the Cu, Fe and S contents in the concentrate to 25%-26%, 16%-19%, 27%-28.5% respectively, and control the copper matte grade, oxygen enrichment concentration and oxygen ore ratio to 72%-73.5%, 80%-81%, and 166-168 m3/t, respectively.
