Abstract:In order to explore new pathways for large-scale and value-added utilization of copper tailings, this study utilized copper tailings to prepare anti-corrosion composite plates. Chemical composition, particle size and phase structure of copper tailings were analyzed by X-ray fluorescence (XRF), laser particle size analysis and X-ray diffraction (XRD). Influence of copper tailings addition on bending strength, compressive strength, density, water absorption, and corrosion resistance of anti-corrosion composite plates was investigated. Results indicated that the maximum incorporation level of copper tailings was 30%. At this point, mechanical properties or corrosion resistance of anti-corrosion composite plates did not show a significant decrease, meeting anti-corrosion and load-bearing requirements for floors in hydrometallurgical workshops. This demonstrated the feasibility of using copper tailings to prepare anti-corrosion composite plates, providing a new idea for large-scale and value-added consumption and utilization of copper tailings.
