Present Situation and Progress of Resource Utilization Technology of Copper Tailings in China

This is an essay in the field of mining engineering. Copper tailings are mainly concentrated in east China, southwest China and central South China, which are stored in dry dumps or wet discharge in tailings pond. The lack of multi-gradient and multi-direction utilization mode, brings great threat to the environment and safety around the mining area. It is an important measure to ensure the safety of resources and environment in mining area to strengthen the technical research on the utilization of domestic copper mine tailings and realize its large-scale consumption. This paper introduces the general situation and distribution of copper mine tailings resources, summarizes the utilization status of copper mine tailings in valuable element recovery, building materials, filling, reclamation and other aspects, and discusses the existing problems in the utilization of copper mine tailings resources and gives a prospect of reasonable development and utilization, providing a reference for further research and application of copper mine tailings resources.
