摘要：

This work reports an efficient reactor, i.e., oxygen-rich side blow furnace (OSBF), for high-lead slag reduction. An OSBF with a cross-sectional area of 8.4 m(2) was applied in an industrial-scale test and the results were compared with those from a traditional high-lead slag reduction reactor, i.e., 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 1.07% and 7.99% 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 = 1.56-1.87 and CaO/SiO2 = 0.8-1.05, lower Pb and Cu contents of the slag can be achieved with Fe/SiO2 = 1.65-1.75 and CaO/SiO2 = 1.0.
