| Abstract: | In this experiment, arsenic sulfide residue was used as raw material and wet process of arsenic slag extraction with copper dichloride acid solution was applied. The research focused on the influences of the dose of copper dichloride, pH of the solution and leaching time on the leaching yield of arsenic during the leaching process with copper dichloride. Besides, the method of producing elemental arsenic from arsenic sulfide residue by reduction of arsenic acid solution with stannous chloride was also discussed. |
