Description

PROCEDE ET DISPOSITIF DE RECUPERATION ET DE VALORISATION DE COMPOSES METALLIQUESMETHOD AND DEVICE FOR RECOVERING AND RECOVERING METAL COMPOUNDS

La présente invention concerne un procédé ainsi qu'un dispositif permettant d'assurer la séparation et la récupération des constituants métalliques et/ou autres constituants valorisables présents dans un matériau composite notamment stratifié matière plastique-métal.The present invention relates to a method and a device for ensuring the separation and recovery of metallic constituents and / or other recoverable constituents present in a composite material, in particular plastic-metal laminate.

L'invention s'applique notamment, sans pour autant être limitée à une telle application, à la récupération du cuivre contenu dans des plaques de stratifiés pour circuits imprimés. On sait que lors de la réalisation de telles plaques constituées d'un support de tissu de verre lié par des résines époxy sur lequel est déposé un revêtement de cuivre a pureté très élevée, on est amené à découper au format désiré des plaques de dimensions relativement importantes, ce qui se traduit par des chutes comprenant une proportion non négligeable de cuivre à pureté très élevée (de l'ordre de 99,95%). Jusqu'à présent, il n'a pas été possible de récupérer ce cuivre par un procédé classique de fusion à haute température étant donné que la mise en oeuvre d' un tel procédé se traduit par la production d'une liaison verre et cuivre conduisant à un bi-sulfure de cuivre non valorisable à ce jour .et l'émission de gaz toxiques résultant de la combustion des résines époxy.The invention applies in particular, without being limited to such an application, to the recovery of copper contained in laminate plates for printed circuits. We know that during the production of such plates consisting of a glass fabric support bonded by epoxy resins on which is deposited a coating of copper of very high purity, it is necessary to cut to the desired format of relatively large plates significant, which results in falls comprising a significant proportion of very high purity copper (of the order of 99.95%). Up to now, it has not been possible to recover this copper by a conventional high-temperature fusion process since the implementation of such a process results in the production of a glass and copper bond leading to a copper bi-sulfide which cannot be upgraded to date. and the emission of toxic gases resulting from the combustion of epoxy resins.

La présente invention s'est fixé pour objectif de réaliser la séparation des composés métalliques et notamment du cuivre, contenu dans un matériau composite grâce à un procédé ne présentant pas les inconvénients mentionnés ci- dessus des techniques antérieures.The present invention has set itself the objective of carrying out the separation of metallic compounds and in particular copper, contained in a composite material by means of a process which does not have the drawbacks mentioned above of the prior techniques.

En conséquence, l'invention concerne un procédé de séparation des constituants métalliques valorisables tels que notamment verre-résine-métal contenus dans un matériau composite notamment stratifié matière plastique-métal caractérisé en ce qu'il consiste à :Consequently, the invention relates to a process for separating recoverable metal constituents such as in particular glass-resin-metal contained in a composite material, in particular plastic-metal laminate, characterized in that it consists in:
