黄钾铁矾渣中银的回收工艺研究
|
Abstract:
银在浸出过程中往往随着黄钾铁矾渣沉淀，且随着浸出温度的升高，黄钾铁矾渣变得越来越稳定，银的回收也越来越困难。在热酸浸出–铁矾法中一般采用超酸浸出或焙烧方法回收银；而在低中温热压中是在浸出过程中添加NaI，高温热压则通常对氧化渣进行预处理的方法来回收银。
Silver often precipitate as jarosite slag in the process of leaching, and with the increase of leaching temperature, the jarosite residue was becoming more and more stable. In hot acid leaching-iron vitriol method, the recovery of silver generally used super acid leaching or roasting method; in low or medium temperature pressure oxidation, NaI was added in the process of leaching, and the high temperature pressure oxidation took usually alkaline pre-treatment method.
