Abstract
527,116. Precipitating silver. MUHLETHALER SOC. ANON., T. March 31, 1939, No. 10157. Convention date, April 15, 1938. [Class 82 (i)] Spent hyposulphite solutions are treated for the recovery of silver in metallic form by bring- ing them into contact with one or more metals such as iron, steel, or copper in the form of an elastic mass made up of entangled filiform elements such as fine or coarse metal wool. The liquid may be caused to flow through the mass at regulated speed, and the silver may be recovered from the mass by melting.
