| Abstract: |
| The effects of reaction pressure, initial acidity of sulfuric acid, leaching temperature, ratio of liquid to solid, and reaction duration on oxygen pressure acid leaching rates of copper and arsenic in black copper mud were investigated by single factor experiment. The results show that, the leaching rate of copper and arsenic is 98.64% and 95.72% respectively under the optimum conditions. Antimony and bismuth in slag are enriched by 7.8 times and 9.5 times of original material respectively. |
