Research on the comprehensive treatment process of the leaching solution of copper smelting electrostatic precipitator dust and arsenic sulfide slag

A combined treatment process of acid leaching solution of electrostatic precipitator dust and arsenic sulfide slag in copper smelting is introduced. The optimum reaction conditions of the leaching solution of copper smelting electrostatic phecipitator dust and arsenic sulfide slag are determined as follows: the amount of copper sulfate added is 1.1 ∶ 1 of theoretical copper to arsenic molar ratio, the reaction temperature is 85 ℃, the reaction time is 2 hours, the mass concentration of copper ion is 15 g/L, and the mass concentration of initial suphuric acid is 30 g/L.
