| Abstract: |
| Nonferrous metallurgical waste slag in China has the characteristics of large annual production, relatively low comprehensive recovery rate and great environmental risks in safe disposal. Comprehensive utilization technologies (hydrometallurgical leaching, metallurgical dressing, pyrometallurgy, bioleaching and building materials production), risk prevention and control technologies (source reduction and ecological restoration, stabilization and immobilization), and safe disposal technologies of nonferrous metallurgical waste slag at home and abroad were elaborated. Principles, characteristics, application scope, advantages and disadvantages of the above technologies were summarized in detail. Based on that, development trend of comprehensive utilization and safety disposal technologies of nonferrous metallurgical waste slag was put forward. |
