| Abstract: |
| The sulfuric acid elution of zinc cyanide on 201*7 anion exchange resin was studied. The effects of main parameters, such as concentration of sulfuric acid, amount of sulphuric acid, temperature and time, on the process were investigated. The results show that the zinc and cyanide can be eluted effectively with 30 g/L H2SO4, volume ratio of H2SO4 on resin of 5 at 30 ℃ for 30 min, the elution rate of cyanide can reach 85% and the elution rate of zinc can reach 97%. |
