摘　　要：目前,氰化法仍是世界黄金冶炼中的主流提金方法,含金物料氰化浸出后产生的氰化尾矿浆经固液分离后形成黄金氰渣,其具有高毒性和高危害性,严重危害环境安全和人体健康,制约着黄金冶金行业的健康发展。因此,如何绿色环保综合利用和处置黄金氰渣尾矿浆,是黄金冶炼行业的研究重点及热点。本文对国内外黄金氰渣尾矿浆的脱氰技术进行综述,对各脱氰方法的优缺点进行详细分析,并对不同技术在工业上的实际应用进行介绍,对黄金行业综合脱氰处理实例进行总结,并对黄金氰渣尾矿浆脱氰技术的发展趋势进行讨论和展望。At present,cyanidation is still the dominant method of gold extraction around the world.The cyanide tailings slurry produced after cyanide leaching of gold containing materials is separated by solid⁃liquid separation to form gold cyanide residue,and the gold cyanide residues with high toxicity and high harmfulness seriously endanger environmental safety and health,and restrict the healthy development of gold metallurgy industry.Therefore,how to use and dispose gold cyanide residues in a green and environmentally friendly manner is the research focus and hot spot of gold industry.In this paper,the cyanide removal technologies of gold cyanide residue slurry were reviewed,the features and the practical industrial application of each technology were introduced in detail.The examples of comprehensive cyanide removal treatments in the gold industry were summarized,and the future development trend of cyanide removal technology of gold cyanide residue slurry in the future industry was discussed and prospected.
