| Abstract: | The loss of copper in electric furnace slag during flash smelting operation is described. In light of production practice, the author introduces some measures for reducing copper content of electric furnace slag to <0.8%: aplication of new type of concentrate nozzles, stabilization of flash furnace slurry, addition of coke powder to flash furnaces, control of the Fe/Si ratio of furnace slag, increasing the time for clarification of copper liquor, and addition of reductants, such as coal or pyrite. |
