| 尾矿是我国产生量最大的大宗工业固体废物，具有资源浪费及环境污染的双重风险。受经济发展水平、矿物加工技术和工艺装备水平的限制，尾矿中部分有价成分未能充分回收，因此其资源化利用与大规模消纳问题亟待解决。在“双碳”目标和“十四五”规划引领下，加快固废行业绿色低碳转型、减轻固废处置压力已成为首要任务，本文首先概述了尾矿的类型及其成分特征，随后剖析了当前资源化利用过程中存在的主要问题，并系统阐述了综合利用率不高的主要原因；在此基础上，重点论述了尾矿在建筑材料领域的综合利用途径；最后，提出了尾矿高效资源化利用的策略，以期为推进“无废城市”建设提供参考。 |
| 英文摘要: |
| Tailings represent the largest source of bulk industrial solid waste in China, posing dual risks of resource wastage and environmental pollution. Constrained by the level of economic development as well as limitations in mineral processing technologies and equipment, a portion of valuable components often remain unrecovered from tailings. Consequently, addressing their resource utilization and large-scale disposal has become an urgent priority. Guided by the "Dual Carbon" goals and the "14th Five-Year Plan," accelerating the green and low-carbon transformation of the solid waste industry and alleviating the disposal pressures have emerged as primary tasks. This paper first outlines the types and compositional characteristics of tailings, then analyzes the major issues in current utilization process, and systematically elucidates the key reasons for the low comprehensive utilization rate. On this basis, it focuses on discussing pathways for the comprehensive utilization of tailings in construction materials. Finally, strategies for achieving efficient resource utilization of tailings are proposed, aiming to provide a reference for promoting the construction of "zero-waste cities." |
