| Abstract: |
| Graphite is renowned as "industrial black gold" and plays an irreplaceable role in critical fields such as high-end mechanical seals, lithium-ion batteries, and graphene preparation. As a dominant mineral resource in China, its export volume accounts for approximately 47.37% of the global total. However, the large-scale development and utilization of graphite resources have generated substantial tailings, leading to severe environmental risks and land occupation issues. Consequently, the resource utilization of graphite tailings has become a major focus for both industry and scientific research. Based on extensive literature review, this paper systematically summarizes recent advances in the resource utilization of graphite tailings, with a focus on three main directions: recovery of valuable components, application in building materials (such as cement concrete, ceramic glass, and roadbed materials), and the development of high-value-added functional materials (including reinforcing fillers, thermal storage materials, and photocatalytic materials). Furthermore, it thoroughly analyzes existing bottleneck issues in the utilization process, such as the complex nature of tailings, low product added value, and an inadequate policy system. Finally, corresponding solutions and development recommendations are proposed to provide reference for promoting efficient and high-value comprehensive utilization of graphite tailings. |
