Abstract: As the ski resort of the Beijing Winter Olympic Games and the important water conservation area and ecological environment support area in the capital of China, green mining is the only way to develop in Chongli District of Zhangjiakou City.The resource utilization of tailings is the key production mode of mining activities.It can turn solid waste resources into treasure, and alleviate the shortage of land and building materials improve the ecological environment and eliminate the harm of tailings pond to the environment.In this paper, the classification of tailings types, the direction and principle of comprehensive utilization of tailings are mentioned.Based on the investigation of tailings, the types of tailings are divided and the comprehensive utilization technology is discussed, taking Chongli Mineral Resources Concentration Area as an example.There are 60 tailings ponds in Chongli Mineral Resources Concentration Area, which are concentrated in the southern mountainous area, mainly iron tailings and gold tailings, covering an area of 3.36 km², and the inventory of tailings is 76.25 million m³.Five types of tailings are divided according to the physical and chemical properties and the proportional relationship between minerals in tailings.Suggestions for comprehensive utilization of various types of tailings are given.Comprehensive utilization can fully tap the secondary utilization potential of tailings, alleviate environmental pressure and realize the purposes of “environmental reconstruction” and “industrial regeneration”.
