湿法冶炼黄金付产品氯化银中银的分析,一般用铅萡包裹灰吹,重量法测定。不具备火试金分析条件也可利用湿法分析。高氯酸——硫酸可以把很多沉淀物,如稀土氟化物、碘化银转化为高氯酸——硫酸溶液。本文确定了高氯酸—硫酸将氯化银转化为溶液的条件,用20m1高氯酸和5m1硫酸可使1g氯化银中的银全部转化;0.2～0.5g试样加15 Wet smelting gold to pay silver chloride product analysis, the general lead ash wrapped blown, gravimetric determination. Wet assay is also available without fire assay conditions. Perchloric acid - sulfuric acid can be a lot of sediment, such as rare earth fluoride, silver iodide into perchloric acid - sulfuric acid solution. This paper identified perchloric acid - sulfuric acid to silver chloride into solution conditions, with 20m1 perchloric acid and 5m1 sulfuric acid can make silver 1g silver all conversion; 0.2 ~ 0.5g sample plus 15
