| Abstract: | Test was conducted on selective leaching of zinc from a kind of flue dust to explore the effects of liquid/solid ratio, pH value, leaching temperature and leaching time on the leaching rate of zinc and arsenic. Results show that with liquid/solid ratio at 2∶1, pH value of 4.0, the selective leaching process at 25 ℃ for 90 min can result in the leaching rates of zinc and arsenic up to 93.92% and 4.12%, respectively. |

| Keywords: | zinc-bearing flue dust selective zinc leaching zinc arsenic |
