摘　　要：黄金矿山尾矿的大量排放与堆积不仅浪费资源和占用土地,还给人类和环境造成一定的危害。黄金尾矿中不仅含有金、银、铜和铅等有价成分及石英和长石等非金属矿物,还含有大量的硅铝氧化物和硅酸盐类物质,具有回收利用价值和广泛的工业用途。从黄金矿山尾矿的组成及危害入手,综述了黄金尾矿资源化利用的两个方向:一是利用焙烧、浸出和浮选等方法回收尾矿中的有价成分;二是对尾矿进行加工处理生产各种工业材料。最后总结了目前黄金尾矿资源化利用存在的问题和未来技术发展方向。the massive discharge and accumulation of gold tailings not only wastes resources and occupies land area,but also causes certain harm to environment and human beings.Gold tailings not only contain non-ferrous metals such as gold,silver,copper,lead,and non-metallic minerals such as quartz and feldspar,but also contain a large number of silicon aluminum oxides and silicate materials,which have the value of recycling and extensive industrial use.Starting from the composition and harm of gold tailings,this paper summarizes two directions for the resource utilization of gold tailings.One is to recover valuable components from tailings by roasting,leaching and flotation.The other is to use tailings to process and produce various industrial materials.Finally,the paper summarizes the existing problems and future technology development direction in the utilization of gold tailings.
