Abstract:
Lead-zinc tailings in China have large stockpiles and a low comprehensive utilization ratio, which have brought potential environmental pollution risks and safety hazards. This work aims to promote the technology progress and practical production of the development and utilization of lead and zinc tailings. The research progress of resource utilization for lead and zinc tailings was systematically analyzed, and the tailings reselection and tailings reprocessing and utilization to prepare cement, bricks, glass-ceramics, and filling materials were overviewed. The advantages and disadvantages of tailing reselection were compared with those of tailing reprocessing and utilization. Tailings reselection and utilization can extract valuable metals, but with high cost and complicated process, and a large amount of tailings still exist after reselection. In contrast, the lead and zinc tailings themselves contain silicon (Si), calcium (Ca), aluminum (Al) and iron (Fe) and other oxidized minerals, and these oxidized minerals can replace clay, shale and cement and other raw materials through reprocess to prepare high-value-added materials, which can achieve a large number of lead and zinc tailings consumption and low cost. It is proposed that the economic value of mine tailings should be evaluated in advance and the green reprocessing and utilization of lead and zinc tailings should be strengthened to achieve tailings recycling, reuse, and reduction. © 2024 Editorial Board of Geology and Exploration.
