| Abstract: |
| Special resin was applied to recover acid and remove iron from copper electrowinning solution. The effects of flow rate, flow direction of adsorption solution and desorption solution on acid adsorption rate and iron retention rate were investigated. The rules of acidity and concentration of iron and copper with continuous adsorption-desorption time were explored. The results show that acid recovery and iron removal rate are 74.03% and 71.57% respectively under the optimal conditions. |
