摘要
氨氰浸出技术自从发明以来就被认为是从含铜难处理金矿资源中选择性回收金的一种有效方法。系统总结了目前国内外氨氰浸金的研究进展,主要包括氨氰浸金的基本原理、浸出动力学研究、溶液化学研究、氨氰浸金实验室实验及工业应用研究现状,对氨氰浸金过程中存在的问题及其未来的发展趋势做了评价。
Since the ammonia-cyanide leaching was developed in 1901, it has been considered as an effective method for selective extraction of gold from the refractory oxidized copper-gold ore. The latest status around the world of gold extraction using the ammonia-cyanide method is systematically reviewed in the present paper, including basic principle of the method, leaching dynamic, solution chemistry, laboratory tests and industrial application. The existing problem is discussed, and future developments are also prospected.
