电场强化氯化铵法浸取毒重石的实验研究

Abstract

Abstract: Electric field intensification process was experimentally employed to leach witherite with NH4Cl.Factors，including the mass ratio of liquid to solid，dosage of NH4Cl，anode current density，reaction temperature，and leaching time etc.，associated with leaching rate were investigated.Results showed that leaching rate of barium was 91.53% when mass ratio of liquid to solid was 5∶1，anodic current density was 900 A/m2，and mass ratio of ore to NH4Cl was 1∶1 at 90 ℃ for 3 h.Compared with the leaching process without electric field intensification，the leaching rate of barium was improved by 10.42%.

Key words: electric field intensification, NH4Cl, witherite, leaching
