配方说明：	Silver Waste Recovery
配方组成：
配制方法：	Add hydrochloric acid to dissolve. If the silver chloride is allowed to stand a few days in contact with an iron sheet in a 5% sulfuric acid solution it will be converted to a black sludge of metallic silver. This is washed well and dissolved in nitric acid, from which the silver nitrate can be crystallized by evaporation. A purer material can be realized by dissolving the silver chloride in cyanide, then plating out on a stainless steel sheet, using an iron or stainless steel anode.
