According to the characteristics of the acid mine drainage such as high concentration of copper ion and acid,an experiment to treat copper-bearing acidic waste water by electrodialysis process was carried out.The results of experiment showed that after multistage electrodialysis processing,the removal rates of copper ion and hydrogen ion in the waste water from the desalting chamber could achieved 97.08% and 99.20% respectively,and the copper,iron and hydrogen ions in waste water were enriched in the concentrated solution,this could provide facilitates for the comprehensive utilization of the metal ions as resource.The experimental study is a helpful exploration for the treatment and resource utilization of copper-bearing acid mine drainage,and is favorable for the sustainable development of mine.
