Abstract:Copper, a non-ferrous metal, is widely used in various industries due to its excellent physical and chemical properties. The main source of copper is from mining, and a large number of tailings are produced after the beneficiation process to enrich copper. The accumulation of tailings in tailings ponds not only occupies land but also causes serious pollution to the surrounding environment due to the residual reagents and heavy metal ions in the tailings. The annual maintenance and management costs of tailings ponds also bring significant economic pressure to enterprises. Improving the comprehensive utilization rate of copper tailings and achieving large-scale consumption of them are important measures to recycle metal resources and eliminate environmental threats. This paper detailed the current status of comprehensive recovery and utilization of resources such as S, Fe, and Cu in copper tailings, and compared the action mechanisms and advantages and disadvantages of different recovery methods. At the same time, it elaborated on the current status of resource utilization of copper tailings in building materials, microcrystalline glass, ceramics, mine filling based on the action mechanisms and application approaches. On this basis, it also summarized the future development direction of comprehensive utilization of copper tailings, providing reference for the development of this field.
