Discussion on the comprehensive utilization of copper tailings under the background of dual carbon
The properties of copper tailings,the relevant policies and current status of comprehensive utilization of copper tailings were systematically reviewed in this paper.The comprehensive utilization direction of copper tailings under the background of dual carbon was further discussed.China has provided a good policy environment for the comprehensive utilization of copper tailings.The comprehensive utilization of copper tailings also shows the characteristics of multiple approaches,directions,and benefits.However,the actual industrial application process still has problems,such as limited methods and low utilization rates.The development of large-scale consumption of copper tailings resources is an important measure to realize the construction of green mines and ecological civilization in China.Under the background of dual carbon,the comprehensive utilization of copper tailings includes two directions:carbon reduction and carbon sink enhancement.The main development direction of copper tailings comprehensive utilization in the future is to realize ecological restoration of tailings pond by adopting efficient improvement measures,increasing the carbon sink of the tailings matrix,and promoting the growth of vegetation carbon pool in mining area as well as establishing the corresponding technical method and standard system.
