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).
Claims5
Apparatus for electrolytically recovering metal, in particular silver, from a photographic processing solution, comprising;
- an anode (41) located in a recovery chamber (51) and a cathode (42) arranged for movement from a first position within the solution to a second position outside the solution as well as a scraper (44) for removing metal deposited on the cathode (42), the cathode being designed as a hollow-cylindrical circular cathode (42) which in the first position surrounds a vertically arranged cylindrical anode (41) and which in the second position is located above the anode (41) and is engaged with the scraper (44) and will remain in engagement therewith until the cathode has returned to the first position.
