Abstract

Procédé de récupération de l'argent contenu dans les films photographiques et cinématographiques. Il comprend une phase de broyage des films, une phase de lavage, rinçage et essorage du produit obtenu par broyage, une phase de filtrage et une phase de séparation mécanique du produit du filtrage, à l'issue de laquelle on obtient des boues à faible hygrométrie, contenant tout l'argent fixé sur les films et des eaux résiduaires. L'invention concerne également le dispositif de mise en oeuvre de ce procédé.
