In this article, the method of sodium hydroxide leaching was adopted to remove arsenic in converter dust. Through single factor experiment, the best process conditions of arsenic leaching were determined. The results indicated that leaching rate of arsenic was more than 95% and that of nickel was less than 0.5% at the condition of the liquid/solid ratio of 7∶1 and the sodium hydroxid concentration of 2 mol/L at 80℃ for 2 hour.
