摘　　要：金尾矿大量堆存不仅占用了宝贵的土地资源,而且存在极大的安全隐患。这些尾矿中部分金属元素和非金属矿物含量较高,具有较大回收价值与资源化利用前景。针对金尾矿的资源化利用,详细阐述了金尾矿回收金、铁、铅等有价金属和石英、长石、绢云母等非金属矿物的技术路径与工艺特点,分析研究了金尾矿活化后作为胶凝材料用于采区充填的技术方案,同时对金尾矿制备混凝土、烧结砖、陶粒、泡沫陶瓷等建筑材料的研究进展进行了综述。最后综合评述了金尾矿资源化利用存在的问题和研究发展方向。The massive accumulation of gold tailings not only occupies valuable land resources,but also has great security risks.These tailings contain high content metallic elements and non-metallic minerals,which has great recovery value and resource utilization prospect.Aiming at the resource utilization of gold tailings,the technical path and technological characteristics of recovering valuable metals such as gold,iron and lead and non-metallic minerals such as quartz,feldspar and sericite from gold tailings were described in detail.The technical scheme of activated gold tailings used as cementation material for filling mining area was analyzed.Meanwhile,the preparation of concrete,sintered brick,ceramite,foam ceramics and other building materials from gold tailings was discussed.Finally,the existing problems and research development direction of gold tailings resource utilization were reviewed.
