The invention relates to an integral recycling method for cathodic tubes, said method being characterised in that it enables the recycling of the glass forming the cathodic tubes and the luminophors formed on the internal face of the screens by the association of the following steps: the cathodic tubes are opened by means of a laser source; dry cleaning is carried out by means of surface treatment agents; and the luminophors are recycled by an acidobasic method in the presence of fluorides. The judicious association of a particular opening mode, a dry surface treatment, and a hydrometallurgical step for treating luminophor powders leads to a method enabling protection of the environment and working station, and an increased material valorisation rate.

La présente invention concerne un procédé de recyclage intégral des tubes cathodiques caractérisé en ce qu'il permet le recyclage des verres qui composent lesdits tubes cathodiques et les luminophores déposés sur la face interne des écrans au moyen de l'association des étapes : d'ouverture desdits tubes cathodiques au moyen d'une source laser ; du nettoyage à sec au moyen d'agents de traitement de surface ; du recyclage des luminophores par voie acido-basique en présence de fluorures. L'association judicieuse d'un mode d'ouverture particulier, d'un traitement de surface à sec et d'une étape hydrométallurgique de traitement des poudres luminophores conduit à un procédé qui permet à la fois : une protection de l'environnement et du poste de travail, et un taux de valorisation matière élevé.
