Abstract: Mine wastewater is mainly produced in the process of mining operation and mineral processing operation. The pollutants in wastewater include heavy metal ion, oil, acid, cyanide pollution, fluoride and so on. Based on the introduction to the source, characteristics and harm of mine wastewater, the most commonly used treatment methods of mine wastewater containing plant organic matter and heavy metal ions, such as ion exchange, adsorption, membrane technology, acid and alkali neutralization, coagulation sedimentation method, chemical precipitation, chemical oxidation, electrochemical method and many other typical wastewater treatment technology are introduced. The basic principle, advantages and disadvantages of each processing method are summarized. The research and development direction of mine wastewater treatment technology in the future is prospected.
