Abstract

1353805 Precipitating silver KODAK Ltd 17 Aug 1972 [20 Aug 1971] 39184/71 Heading C7D A process for the recovery of Ag from wash water resulting from washing fixed photographic material carrying residual fixer solution comprises contacting the wash water with steel wool to exchange the Ag contained in solution in the wash water with the Fe. A fixed film 20 passes in the direction of the arrows through wash tanks 10, 11. Tank 11 is supplied with water through inlet 12, the water passing into tank 10 through pipe 14 and into a cartridge 17 containing the steel wool where the exchange takes place. The photographic material is washed with 20-60 parts of water to each part of fixer solution carried by the material.
