| Abstract: | A pressure leaching process was adopted in order to recover copper and zinc in the flue dust from copper smelting. Effects of temperature, pressure, initial acid concentration and leaching time on the final leaching rates were investigated. The results show that a 3 h-pressure leaching at 160 ℃, with the pressure at 1.2 MPa and an initial acid concentration of 130 g/L, can lead to the leaching rate of copper and zinc up to 98.9% and 97.8%, respectively. |

| Keywords: | flue dust from copper smelting pressure leaching leaching rate copper zinc oxidation |
