摘要:
随着环保要求越来越高，金矿资源日趋贫、细、杂，选矿难度越来越大，尾渣的资源化利用成为研究热点。针对焙烧氰化尾渣中金的提取，根据金不同的嵌布状态，以焙烧氰化尾渣中包裹体分解的有效性，将提金方法分为氧化铁包裹金的提取、硅酸盐包裹金的提取及综合提金三大类，并分析了各类别中不同工艺的优缺点及应用的适应性，为焙烧氰化尾渣中金提取工艺的选择提供参考借鉴。

Abstract:
With higher environmental protection requirement and gold resources becoming low-grade,fine and impure,mineral processing is more challenging.Therefore,tailings utilization as resources becomes a hot study topic.In the study of gold extraction from roasting cyanide tailings,according to the different embedding status of gold,gold extraction methods are classified as iron oxide inclusion gold extraction,silicate inclusion gold extraction and comprehensive gold extraction as far as the effectiveness of inclusion disintegration in roasting cyanide tailings goes.At the same time,the advantages and disadvantages as well as its applicability of each method are analyzed,providing reference for the selection of gold extraction method for roasting cyanide tailings.
