Japan, Australia Peko rich ore processing smelter bismuth-containing 0.4% to 1% of the copper concentrates, the output of the converter dust content (%); Bi 10, Pb 27, Zn 12, Cu 0.2, S 12, with a venturi washed with wash filter cake was leached with sulfuric acid addition salt, a washing and replacement with scrap iron, bismuth output 40% to 65% bismuth, bronze drum stove with an electrostatic precipitator dust granulated, and the reflection furnace The coke powder, soda ash and quartz powder are reduced and smelted together, and the crude sulphide is more than 90%, and the Pb is less than 5%. The refining pot is put into the refining process for fire refining. The process flow is shown in Fig. 1. Figure 1 Flow chart of recycling process of Guofu Factory The process includes leaching, replacement, reduction smelting, fire refining and other processes, and rationally utilizes the combination of copper converter and blast furnace soot, wet method and fire method. The process is compact and the program arrangement is reasonable, which is worthy of promotion.
