Abstract:The generation and storage of copper smelting slag poses serious ecological and environmental safety risks. How to make full use of copper smelting slag, achieve comprehensive utilization of secondary resources, and reduce environmental safety risks has become a current research hotspot. Purpose: By integrating and summarizing the existing research results and knowledge in the field of comprehensive utilization of copper smelting slag, this study explores the application prospects of copper smelting slag in road base materials and puts forward relevant suggestions. Method: Conduct a systematic review and analysis of relevant literature. Conclusion: The use of copper smelting slag to prepare road base materials can not only utilize copper smelting slag on a large scale, reduce potential environmental pollution problems caused by the discharge and storage of copper smelting slag, but also effectively solve the problem of limited sources of raw materials for traditional road base materials, which is very important for regional infrastructure construction and sustainable development of the ecological environment are of great significance.
