摘要/Abstract

摘要： 铜尾矿(CTs)作为大宗工业固体废弃物之一,其综合资源化利用一直受到社会广泛关注。目前,我国CTs累计堆存量约占尾矿总量的四分之一,仅次于铁尾矿,储量庞大。然而,我国尾矿资源回收利用技术发展较为缓慢,CTs资源利用效率低,亟需探索合理的CTs高效处理方式。CTs在水泥及混凝土领域的研究应用较多,但都侧重于某一方面性能或应用研究,总结性的综述性文献相对较少。本文对CTs在水泥工业生产和在混凝土中应用两方面进行合理的分类,综述了CTs的基本性质和其在水泥及混凝土中的应用特点和优势,并对CTs中重金属离子浸出控制及活性激发技术进行了总结和展望,以期对CTs的综合高效利用提供技术及理论上的支持。

Abstract: Copper tailings (CTs), as one of the major industrial solid wastes, have garnered significant attention due to their potential for comprehensive resource utilization. Currently, the cumulative reserves of CTs in China account for approximately one-quarter of the total tailings volume, second only to iron tailings, indicating a large reserve. However, the development of tailings recycling technologies in China is relatively slow, and the utilization efficiency of CTs remains is low. It is urgent to explore a reasonable and efficient methods for CTs. While research on the application of CTs in cement and concrete has been extensive, these studies typically focus on specific aspects of performance or application research, with relatively few comprehensive reviews available. This paper categorizes the use of CTs in cement production and concrete application, reviews the fundamental properties of CTs, as well as their application characteristics and advantages in cement and concrete, and provides a summary and outlook on the control of heavy metal ion leaching and activation techniques for CTs. The goal is to offer technical and theoretical support for the comprehensive and efficient utilization of CTs.
