| Abstract: | Lead sulfide concentrates produced by Corporation of West Mining and imported concentrates containing high zinc were used as the test materials, respectively. The semi industrial experiments of matte making reduction smelting of the concentrates were carried out in a reverberatory furnace with area of 1?m 2. The experiment results show that the contents of SO 2 in exhaust gas are lower than that of the national standard, the ratio of sulfur fixation, direct and total recovery of lead are higher than 96%, 87%, and 96%, respectively, and the crude lead has high quality that can be directly used in electrolytic refining. It is showed that the new process is feasible to be put into use in industry production on the large scale. |
