铜尾矿建材化应用研究现状及矿物组成影响作用规律

我国铜尾矿排放及储量巨大,造成环境污染和资源浪费。铜尾矿矿物成分复杂、颗粒粒度较细等问题限制了铜尾矿的高效高附加值利用。本文综述了铜尾矿的矿物属性、物理化学性能特征及其在建材化应用过程中的技术和控制要求,从铜尾矿用于蒸压加气混凝土、水泥基材料、水泥熟料、砖、微晶玻璃、多孔材料、充填材料等多个途径,总结了铜尾矿的主要应用方式、作用特征和主要成分的影响作用规律。为铜尾矿等固废生产型企业协同建材行业系统解决尾矿资源化问题提供参考,协同建材行业的发展方向和产品要求,提出了未来尾矿资源建材化处置的关键性问题,为真正实现尾矿的产品资源化利用提供支持。

Research Status of Building Material Application of Copper Tailings and Influencing Rules of Mineral Composition

The copper tailings discharge and reserve are huge in China, resulting in environmental pollution and resource waste. The complex mineral composition and fine particle size of copper tailings limit the efficient and high value-added utilization of copper tailings. This paper summarized the mineral properties, physical and chemical properties of copper tailings, and the technical and control requirements in the industrial application of building materials. The main application modes, action characteristics and the influencing rules of main components of copper tailings were summarized from the application ways of copper tailings in autoclaved aerated concrete, cement-based material, cement clinker, brick, glass-ceramics, porous material and filling material. It provides reference for copper tailings and other solid waste production enterprises to cooperate with building materials industry to systematically solve the problem of tailings recycling. In coordination with the development direction and product requirements of building materials industry, the key problems of building materials disposal of tailings resources in the future are put forward, which provides support for the real realization of resource utilization of tailings products.
