摘要
本文对ＫＩ—Ｉ２溶液体系从废可伐镀金件上回收金的工艺过程进行了研究。考察了溶金介质、溶金温度、溶金液中ＫＩ／Ｉ浓度比和ＫＩＯ３加入量等因素对镀件退金效果的影响．确定了镀件退金和溶金液电解还原金的适宜工艺条件。研究所得结果对工业实践有指导意义．
This paper studied the technological process of recovering gold from waste goldclad components with KI-I2 solution.The optimum technological conditions of resolving gold from goldclad components and electrolyzing resolving soluition containing gold were determined through investigating the effects of mediums,temperatures,concentration ratios of KI, I2 and quantity of KIO3 added in resolving solution on the result of returning gold. The results obtained from the research would have guiding significence to industrial practice.
