| Abstract: | SO2 reduction leaching process is an important process in hematite zinc smelting process.Behaviors of elements such as zinc,iron,copper,arsenic and silicon during SO2 reduction leaching were studied.The results show that zinc leaching rate is 97%and leaching slag suitable for copper lead smelting is obtained under the conditions including leaching temperature of 110℃,terminal acid concentration of 30 g/L,and leaching time of 2 h. |

| Keywords: | zinc acid leaching residue SO2 reduction leaching hematite method leaching rate |
