从硫代硫酸盐浸出贵液中回收金银的研究现状
|
摘要
硫代硫酸盐法是一种有效的浸出金银技术,而浸出贵液中金银难以高效回收,制约了该方法的发展。本文综合评述了金属置换、活性炭吸附、树脂吸附、溶剂萃取和电沉积等从硫代硫酸盐浸出液中回收金银技术的研究现状,在此基础上总结了今后的发展方向和研究重点。
The thiosulfate is an effective lixiviants for gold and silver leaching. However,it is difficult to recover the precious metals efficiently from the thiosulfate pregnant solution,which restricts the application of the technology. The research status of the recovery techniques are reviewed,including cementation,activated carbon adsorption,resin adsorption,solvent extraction and electro-deposition. The research direction and focus are also summarized.
