【Abstract】 With the development of information technologies, the amount of waste electrical and electronic equipments (WEEE) continues to increase rapidly, which is characterized by an abundance of quantity, hazard effect to health, high commercial value, and difficult recovery. The different recycling methods for WEEE were summarized, including incineration process, hydrometallurgical approach, mechanical separation, and thermal process. Advantages and disadvantages of various processing methods of WEEE were presented in detail. The attention was concentrated on processing characteristics of mechanical separation, hydrometallurgical approach, and thermal process. Finally, the new development trends of WEEE processing technologies are commented and predicted.更多还原
