| Abstract: |
| The effects of bubbling speed, concentration of sulfuric acid, temperature, L/S, and leaching time on leaching rates of copper and arsenic from black copper slag were investigated by single factor experiment. The results show that leaching rate of copper and arsenic is 94.4% and 92.1% respectively under the optimum conditions including bubbling speed of 0.8 m3/h, concentration of sulfuric acid of 1.5 mol/L, leaching temperature of 80 ℃, L/S=6, and leaching time of 3 h. |
