摘　　要：根据生产工艺状况,按照时间进度,对采用富氧底吹自热熔炼的“三连炉”系统进行为期一年的生产数据跟踪记录,通过对数据进行统计分析,探究杂质元素Pb、Zn、As、Sb、Bi和Ni的分布走向。结果表明:入炉混合料中,返回配料的铅占总铅的45.57%,主要集中在渣精矿和吹炼渣中;返回配料中的镍占总镍的36.43%,也主要集中在渣精矿和吹炼渣中;铋主要富集在熔炼锅炉灰中返回系统配料,锑主要富集在渣精矿中返回系统配料,这2种杂质元素在阳极板中的含量仅次于镍;其余杂质元素返回配料的比例不是很大。以上为后续配矿和渣选矿工艺的优化提供参考依据。Based on the production process status and time schedule,a one-year production data tracking record will be conducted on the“triple furnace”system using oxygen-enriched bottom-blowing self heating melting.Through statistical analysis of the data,the distribution trends of impurity elements Pb,Zn,As,Sb,Bi,and Ni will be explored.The results showed that in the furnace feed mixture,the lead returned accounted for 45.57%of the total lead,mainly concentrated in the slag concentrate and blowing slag;the nickel returned accounted for 36.43% of the total nickel,also mainly concentrated in the slag concentrate and blowing slag;percentages of the rest of the impurity elements returned were little;bismuth was mainly enriched in the melting boiler ash returned to the system,antimony was mainly enriched in the slag concentrate returned to the system,and the content of the two impurity elements was only second to nickel in the anode plate.The above provides a reference basis for the subsequent optimization of ore allocation and slag beneficiation process.
