中文摘要：

氰化法是目前黄金企业生产普遍采用的方法,但氰化法浸金对产金区生态环境影响较大,尤其是对地下水污染严重,现场操作人员的安全风险较高,在一些国家和地区氰化法提金已受到限制使用。硫代硫酸盐体系因其对环境影响小、无毒、安全、浸金速率快以及能处理氰化法难处理的含铜含碳难冶炼矿石等优点,已被认为是目前最有望取代氰化法浸出及回收金的浸出剂。但由于硫代硫酸盐提金工艺试剂消耗量大以及缺乏一种有效回收金的方法,导致该法一直未能应用于工业生产。从相关文献可知,硫代硫酸盐浸金液中回收金的方法较多,其中置换法是目前能有效回收金的方法之一,且研究较多。在综述硫代硫酸盐提金机制的基础上,概述了锌、铜、铝、铁以及其他金属置换法回收金的机制、研究现状和存在的问题,提出了今后的研究方向,为硫代硫酸盐的大规模应用研究提供一定的科学理论参考。

英文摘要：

Cyanidation is adopted widely in gold industries. However, the cyanidation leaching for gold has a harmful influence on the environment, especially the underground water and operation workers. In some countries and regions, cyanidation has been inhibi- ted. Since the thiosulphate system is non-toxic, safe, less adverse to the environment, and can leach faster than cyanide and extract gold from refractory ores （copper-gold ores and carbonaceous ores） which cannot be resolved by cyanidation leaching, the thiosulphate leaching of gold has been widely accepted by researchers around the world as a potential alternative lixiviant for the leaching and recov- ery of gold. High consumption of reagents and the lack of a cheap process for recovering gold have made thiosulfate leaching uneconom- ical up to date. Nevertheless, the cementation which was one of the most effective methods of recOvery of gold at present was widely re- searched. In this paper, the mechanism of thiosulfate leaching gold and the gold cementation from leaching solution with metals （ zinc, copper, aluminum and iron） were reviewed respectively. It also analyzed the present problems of cementation and its application pros- pect in order to provide scientific theoretical reference for thiosulfate used in gold industry.
