摘　　要：随着黄金的不断开采,黄金尾矿的堆积量逐年增加,不仅浪费大量土地、破坏周边环境,而且危害人体健康。氰化尾渣的安全处理处置始终是黄金行业关注的热点问题,而黄金尾矿中金、银、铜、铅等金属元素,石英和长石等非金属矿物,以及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。黄金尾矿的综合利用对于黄金行业的健康发展和自然资源保护具有重要意义。针对黄金行业不同提金工艺产生的尾矿,包括金矿石氰化尾渣、金精矿氰化尾渣、堆浸氰化尾渣及浮选尾矿的综合利用进行综述,以期为黄金尾矿的综合利用研究提供参考。The accumulation of gold tailings annually with continuous gold mining not only has wasted large amounts of land,damaged surrounding environment,but also even jeopardized human health.Safe treatment and disposal of cyanide tailings residue has always been hot-spot in gold industry,while gold,silver,copper,lead and non-metallic minerals such as quartz and feldspar as well as silicon aluminum oxides,silicate materials in gold tailings are worth recovering and have wide industrial application potential.The comprehensive utilization of gold tailings is significant in the healthy development of gold industry and natural resources protection.Review of the comprehensive utilization of the tailings generated from different gold extraction processes in gold industry,such as cyanide tailings residue of gold ores,gold concentrates and heap leaching and flotation tailings is conducted,providing reference for the study of comprehensive utilization of gold tailings.
