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.
