| Abstract: | The catalysis-acid leaching process of copper bismuth sulphide dregs is introduced. The effects of acidity, temperature, catalyst, oxide on the process are analyzed. The process parameters are obtained. The cupric sulfate quality is accord with the standard(GB437-93). Over 96 percent of copper was leached. Copper, bismuth, sulphur, arsenic in dregs can be effectually separated and can be comprehensive utilization. The waste gas and waste water yielded in the process can be direct discharged. The process has simple equipments and short flow, low cost. Economical benefit is good. |
