目前文献已报导研发多种非氰浸金试剂.因无毒、价格低廉、浸出率高,并且在处理含碳、含铜金矿石方面具有优异的性能,硫代硫酸盐被认为是最有发展潜力的非氰提金试剂.传统的铜?氨?硫代硫酸盐浸金体系得到广泛研究,但经过多年的工艺改进与发展,该浸出体系仍面临一些关键难题.为了降低硫代硫酸盐的消耗,研究者采用镍基、钴基和铁基催化剂替代铜,并进行一系列的工艺开发研究.针对无氨体系,研发包括氧?硫代硫酸盐、铜?硫代硫酸盐、铜?乙二胺?硫代硫酸盐、铁?乙二胺?硫代硫酸盐、铁?草酸?硫代硫酸盐等多种非氨?硫代硫酸盐浸金体系.作者系统总结目前以硫代硫酸盐为基础的浸金体系的基本理论和工艺发展现状,重点阐述无氨硫代硫酸盐浸金工艺的技术研究现状,并针对性详细介绍含氨基、羧基或羟基官能团的有机配体添加剂对硫代硫酸盐浸金的潜在影响.探讨加快硫代硫酸盐体系工业应用所面临的机遇和挑战.“,”Numerous non-cyanide leaching lixiviants have been developed, among which thiosulfate is considered the most promising alternative to cyanide due to its non-toxicity, low price, high leaching rate and excellent characteristics in dealing with carbonaceous and copper-bearing gold ores. The traditional copper?ammonia?thiosulfate system has been studied extensively. However, with many years of process development, there are still some problems and challenges with this gold leaching system. A series of studies using nickel-, cobalt- and ferric-based catalyst to substitute copper have been conducted with the purpose of reducing the consumption of thiosulfate. A variety of non-ammonia thiosulfate leaching systems including oxygen?thiosulfate, copper?thiosulfate, copper?EDA?thiosulfate, ferric? EDTA?thiosulfate, and ferric?oxalate?thiosulfate leaching systems have been also developed to eliminate the potential side-effect of ammonia. In this review, the basic theory and process development of some main gold leaching systems based on thiosulfate solutions were systematically summarized to illustrate the research status on thiosulfate leaching process. The potential effects of various additives such as organic ligands containing amino, carboxyl or hydroxy functional groups on gold thiosulfate leaching were described in detail. The potential opportunity and challenge for promoting the industrial development of thiosulfate-based gold leaching systems were also discussed.
