Abstract

A process for the treatment and recovery of materials from the production and development of photographic and x-ray films. The process substantially includes the following operating stages: a first stage involving the shredding of the said materials; a second stage involving oxidation of the metallic silver to ionic silver; a third stage for solubilization of the silver salt in water; a fourth stage for the recovery of the metallic silver; a fifth stage for solubilization of the gelatin in an alkaline bath; a sixth stage for recovery of the gelatin; a seventh stage involving the washing, rinsing and drying of the polyester; an eighth stage for drying the polyester.
