| Abstract: |
| In this work, the properties of copper tailings and the relevant policies of copper tailings comprehensive utilization as well as the comprehensive utilization status were systematically reviewed. And 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 tai lings. The comprehensive utilization of copper tailings also shows the characteristics of multi-channel, multi-direction and multi-income. However, the actual industrial application process of copper tailings still has problems such as single mode and low utilization rate, and 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, which are 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 for copper tailings, increase the carbon sink of tailings matrix and promote the growth of vegetation carbon pool in mining area as well as establish the corresponding technical method and standard system. |
