氰化银法生产氰化银钾的生产实践

Practice of silver potassium cyanide production with silver cyanide method

白银经硝酸溶解后,与氰化钠反应生成氰化银沉淀,氰化银经氰化钾络合溶解生成氰化银钾,氰化银钾溶液经过蒸发浓缩后,进行冷却结晶,氰化银钾晶体经脱水、洗涤和干燥后制成成品。

The silver dissolved in nitric acid follow by reaction with sodium cyanide to produce silver cyanide precipitation,then,through potassium cyanide complexation and dissolution,the silver potassium cyanide was prepared with silver cyanide.The silver potassium cyanide solution evaporated and concentrated follow by cooling and crystallization.The final product of silver potassium cyanide crystal was prepared after dehydration,washing and drying.
