| Abstract: | The inflow and outflow of chlorine in the process of zinc hydrometallurgy system is analyzed in this paper, and the experimental study of dechlorination test of copper residue test waS done, the condition test is optimized aS the following ： the extraction temperature is 70 - 75 ℃, the response time is 45 - 55 rain, the concentration of copper ion is 1 - 2.5 g/L, pH value is 2. 5-3.0, the solid to liquid ratio is 30：1, the particle size of copper scale is - 120 mesh, take up 90%, under this condition, the deehlorination rate can reach 60.3%, and based on the optimized conditions, the average dechlorination rate can reach 47.02% in the industrialization operation. |
