Silver extraction or silver recovery is a high profitable business. Silver extraction means remove the silver from the used film, photograph and other silver content materials.
Every film and photograph is coated with a thin layer of silver. During image formation, silver transfers from image portion of film to fixing solution (fixer). After some time fixer solution becomes saturated and stops working.
