Abstract
This work reports an efficient reactor ie oxygenrich side blow furnace OSBF for highlead slag reduction An OSBF with a crosssectional area of 84 m2 was applied in an industrialscale test and the results were compared with those from a traditional highlead slag reduction reactor ie blast furnace BF with which an additional electric heating fore well EHFW was connected for slag cleaning By using the OSBF Pb and Cu recoveries were raised by 107 and 799 compared with those from the traditional BF+EHFW respectively The optimal slag type for recovering metal values in the OSBF was also analyzed Within the range of Fe/SiO2 = 156–187 and CaO/SiO2 = 08–105 lower Pb and Cu contents of the slag can be achieved with Fe/SiO2 = 165–175 and CaO/SiO2 = 10
