Abstract[English]
The present invention is in the field of metal recycling and concerns a process for the recovery of rare earth elements (REE) and platinum group metals (PGM). The process comprises the steps of preparing a metallurgical charge, comprising PGM- bearing catalysts, REE-bearing swarf and fluxing agents; feeding the metallurgical charge to a smelting furnace operating in reducing conditions; smelting the metallurgical charge, thereby obtaining a liquid Fe-bullion containing the majority of the PGM, and a liquid slag containing the majority of the REE; and, separating the bullion and the slag; wherein the REE-bearing swarf and the PGM-bearing catalysts are smelted simultaneously. The process provides a unique synergy of smelting PGM-bearing catalysts and REE- bearing permanent magnets together, resulting in the recovery of PGM and REE in a single process.[French]
La présente invention se rapporte au domaine du recyclage de métaux et concerne un procédé de récupération d'éléments de terres rares (ETR) et de métaux du groupe du platine (MGP). Le procédé comprend les étapes consistant à préparer une charge métallurgique, comprenant des catalyseurs contenant des MGP, des copeaux contenant des ETR et des agents de fluxage ; à introduire la charge métallurgique dans un four de fusion fonctionnant dans des conditions réductrices ; à faire fondre la charge métallurgique, ce qui permet d'obtenir un lingot de Fe liquide contenant la majorité des MGP, et un laitier liquide contenant la majorité des ETR ; et à séparer le lingot et le laitier ; les copeaux contenant les ETR et les catalyseurs contenant les MGP étant fondus simultanément. Le procédé fournit une synergie unique de fusion de catalyseurs contenant des MGP et d'aimants permanents contenant des ETR ensemble, conduisant ainsi à la récupération de MGP et d'ETR dans un seul procédé.
