摘      要：An interphase migration and enrichment model of lead and zinc during molten copper slag depletion was *** occurrence of various components in copper slag was predicted using sulfur-oxygen potential calculations and confirmed through high-temperature *** recovery rate of copper can reach 90.13%under the optimal conditions of 1200°C,an iron to silicon mass ratio of 1.0,3 wt.%ferrous sulfide,and a duration of 45 ***(54.07 wt.%)and zinc(17.42 wt.%)are found in the flue dust as lead sulfate,lead sulfide,and zinc oxide,while copper matte contains lead(14.44 wt.%)and zinc sulfide(1.29 wt.%).The remaining lead and zinc are encapsulated as oxides within the fayalite phase.
