Abstract
A device for electrolytically recovering metal, in particular silver, from a photographic processing solution, said device having an anode located in a recovery chamber and a movably arranged cathode as well as a scraper for removing metal, in particular silver, deposited on said cathode. For the purpose of electrolytically depositing metal (17), cathode (12, 32, 42) is held stationary in its operating position within the solution (16). For removal of the metal, the metal-loaded cathode (12,32, 42) is moved out of its operating position within the solution (16) and is brought into engagement with the scraper (14, 20, 34, 44) arranged outside the solution (16). Subsequently, the cathode (12,32, 42) freed from metal (17) returns to its operating position within the solution (16) for a repeated electrolytic deposition of metal (17).
