Abstract:
(EN) The present invention relates to a method for concentrating and recovering noble metals from printed circuit boards of discarded mobile phones and catalysts of discarded cars using discarded nonferrous slag, which is industrial waste discharged from a process for refining nonferrous metals such as copper, lead, zinc and the like, and more specifically, to a method for concentrating and recovering gold, silver, platinum, palladium, rhodium and the like contained in printed circuit boards of discarded mobile phones and catalysts of discarded cars by melting discarded nonferrous slag, printed circuit boards of discarded mobile phones and catalysts of discarded cars at a high temperature through a single process to reduce and separate iron oxide contained in the discarded nonferrous slag and simultaneously melting and separating copper, iron, tin, and nickel contained in the printed circuit boards of discarded mobile phones to use the generated iron, copper, tin, and nickel alloy as a collector metal for noble metals. The method for concentrating and recovering noble metals from printed circuit boards of discarded mobile phones and catalysts of discarded cars using discarded nonferrous slag of the present invention comprises the steps of: mixing and melting discarded nonferrous slag and a solvent, which is a slag composition controller; inserting printed circuit boards of discarded mobile phones and catalysts of discarded cars to the obtained molten metal to melt the same; and maintaining the same for a predetermined amount of time to separate the same into a noble metal-collected alloy phase and a slag phase containing no noble metals. In addition, the present invention relates to a method for recovering valuable metals such as iron, copper, tin, nickel and the like in addition to noble metals such as gold, silver, platinum, palladium, and rhodium from printed circuit boards of discarded mobile phones and catalysts of discarded cars, and recycling the generated slag without environmental problems. According to the present invention, the amount of the generated alloy phase is increased without using a collector metal for noble metals such as copper, iron, lead, and nickel and carbon as a reducing agent which increase processing costs by using discarded nonferrous slag, which is industrial waste discharged from a process for refining nonferrous metals such as copper, lead, zinc, and the like, as a solvent, which is a slag composition controller, and a noble metal collector simultaneously, and using a plastic component contained in printed circuit boards of discarded mobile phones as a reducing agent, and thus an alloy phase and a slag phase can be readily separated, thereby simultaneously reducing processing time and minimizing the amount of a solvent such as alumina (Al2O3), quicklime (CaO), magnesia (MgO), iron oxide (FeO) and silica (SiO2). Accordingly, noble metals such as gold, silver, platinum, palladium, rhodium and the like can be concentrated and recovered through a single process by simultaneously treating different industrial waste such as printed circuit boards of discarded mobile phones and catalysts of discarded cars, and waste material can be recycled to be used as a material for the high-technology industry, and thus it is possible to maximize the coefficient of utilization of noble metal resources in resource-poor Korea, which depends on imports for all of noble metal resources.
(FR) La présente invention concerne un procédé de concentration et de récupération de métaux nobles de cartes à circuit imprimé de téléphones mobiles mis au rebut et de catalyseurs de véhicules mis au rebut par utilisation de scories non ferreuses mises au rebut, qui constituent les déchets industriels rejetés d'une opération de raffinage de métaux non ferreux tels que le cuivre, le plomb, le zinc et analogues et, plus particulièrement, un procédé de concentration et de récupération d'or, d'argent, de platine, de palladium et de rhodium, et analogues, contenus dans les cartes à circuit imprimé de téléphones mobiles mis au rebut et dans les catalyseurs de véhicules mis au rebut par fusion de scories non ferreuses mises au rebut, des cartes à circuit imprimé de téléphones mobiles mis au rebut et des catalyseurs de véhicules mis au rebut à une température élevée et en une seule opération, en vue de réduire et séparer l'oxyde de fer contenu dans les scories non ferreuses mises au rebut, et par fusion et la séparation simultanées du cuivre, du fer, de l'étain et du nickel contenus dans les cartes à circuit imprimé de téléphones mobiles mis au rebut pour utiliser l'alliage de fer, de cuivre, d'étain et de nickel généré comme métal collecteur de métaux nobles. Le procédé de concentration et de récupération de métaux nobles de cartes à circuit imprimé de téléphones mobiles mis au rebut et de catalyseurs de véhicules mis au rebut par utilisation de scories non ferreuses mises au rebut fait appel aux étapes consistant : à mélanger et à faire fondre les scories non ferreuses mises au rebut et un solvant, qui est un régulateur de composition de scories; à introduire les cartes à circuit imprimé de téléphones mobiles mis au rebut et les catalyseurs de véhicules mis au rebut dans le métal en fusion obtenu pour les faire fondre; et à les maintenir pendant une durée prédéterminée de façon à les séparer en une phase d'alliage de métaux nobles collectés et une phase de scories ne contenant pas de métaux nobles. De plus, la présente invention concerne un procédé de récupération de métaux exploitables tels que le fer, le cuivre, l'étain, le nickel, et analogues, en plus de métaux nobles comme l'or, l'argent, le platine, le palladium et le rhodium de cartes à circuit imprimé de téléphones mobiles mis au rebut et de catalyseurs de véhicules mis au rebut, et de recyclage des scories générées sans entraîner de problèmes environnementaux. Selon la présente invention, la quantité de la phase d'alliage générée est augmentée sans l'utilisation d'un métal collecteur de métaux nobles tels que le cuivre, le fer, le plomb et le nickel ni de carbone comme agent de réduction qui augmentent les coûts de traitement par utilisation de scories non ferreuses mises au rebut, qui constituent les déchets industriels rejetés d'une opération de raffinage de métaux non ferreux tels que le cuivre, le plomb, le zinc, et analogues, comme solvant, qui constitue simultanément un régulateur de composition de scories et un collecteur de métaux nobles, et par utilisation d'un constituant plastique contenu dans les cartes à circuit imprimé de téléphones mobiles mis au rebut comme agent de réduction et, ainsi, une phase d'alliage et une phase de scories peuvent être séparées facilement, en réduisant ainsi simultanément le temps de traitement et en minimisant la quantité de solvants tels que l'alumine (Al2O3), la chaux vive (CaO), la magnésie (MgO), l'oxyde de fer (FeO) et la silice (SiO2). Par conséquent, les métaux nobles comme l'or, l'argent, le platine, le palladium, le rhodium, et analogues, peuvent être concentrés et récupérés en une seule opération par traitement simultané de différents déchets industriels tels que des cartes à circuit imprimé de téléphones mobiles mis au rebut et des catalyseurs de véhicules mis au rebut, et le matériau de rebut peut être recyclé pour utilisation en tant que matériau destiné à l'industrie de la haute technologie, d'où la possibilité de maximiser le coefficient d'utilisation de ressources en métaux nobles de la Corée pauvre en ressources, qui dépend des importations pour toutes les ressources en métaux nobles.
