SMPTE Tutorial Paper: Silver Recovery Management for Motion-Picture Laboratories

Paul J. Mutter, Steven J. Powell

To aid in silver recovery from motion-picture film, several possible layouts have been studied as a means of estimating silver concentrations at various locations in a process. This article reviews several recovery methods, such as precipitation, steel-wool cartridges, electrolytic cells, and ion-exchange resins. Methods of chemical analysis are discussed, mathematical equations for estimating silver concentrations are given, and an analysis of the cost-effectiveness of the various silver-recovery methods is included.
