| Abstract: |
| In this paper, the leaching solution of certain copper smelter flue dust was taken as the raw material, and the tests on recovery of copper were carried out by sulfide precipitation method. Based on the analysis of the main composition of the flue dust leaching solution, the effects of sodium sulfide dosage, reaction time and temperature on the copper precipitation rate were investigated, and the optimum technological conditions were obtained. The optimum condition is: the ratio of sulphur to copper 1.2, reaction temperature 80℃ and reaction time 1h. Under this condition, the precipitation rate of copper can reach 98.82%, while that of arsenic and zinc is only 0.08% and 0.41%. The copper content in the precipitated residue is as high as 60.4%. |
