【摘要】 针对当前甘肃省祁连山一带金属尾矿渣堆存造成的生态环境破坏问题，通过实地调研，重点选取该地区酒泉境内金尾矿、铜尾矿、铁尾矿三种尾矿渣的代表性样品为研究对象，测试分析其密度、粒径分布、化学成分、矿物组成、重金属浸出毒性及放射性等理化性质，并探讨上述尾矿渣制备建筑材料的可行性及在建材方面的应用方向。研究结果表明，三种尾矿渣表现出明显的资源属性、经济属性等特点，该研究结果为该地区金属尾矿渣的资源化利用提供基础参考。更多还原

【Abstract】 In view of the current ecological environment damage caused by the accumulation of metal tailings in the Qilian Mountains of Gansu Province, through on-the-spot investigation, the representative samples of gold tailings, copper tailings and iron tailings in Jiuquan area were selected as the research objects, and its density, particle size distribution, chemical composition, mineral composition, heavy metal leaching toxicity and radioactivity were tested and analyzed. The feasibility of preparing building materials with the above tailings and the application direction in building materials were discussed. The results showed that the three kinds of tailings all showed obvious resource attributes and economic attributes, which provided reference for the resource utilization of metal tailings inthe region.更多还原
