从金的湿法冶金工艺来说,目前大多采用氰化钠浸出工艺,即金和银均以Au(CN)_2~-和Ag(CN)_2~-络离子形式存在。为分离和富集金湿法冶金工艺流程中的金,所用的离子交换树脂必须能够从氰化物溶液中有效地吸附金和银。为此,我所合成了353E树脂,本文则介绍该树脂从氰化物溶液中吸附金和银的性能。 From gold hydrometallurgical process, most of the current use of sodium cyanide leaching process, that gold and silver are Au (CN) _2 ~ - and Ag (CN) _2 ~ - ions form. For the separation and enrichment of gold in the gold hydrometallurgical process, the ion exchange resin used must be able to efficiently adsorb gold and silver from the cyanide solution. To this end, I have synthesized 353E resin, this article describes the resin from the cyanide solution adsorption of gold and silver performance.
