The invention provides an enrichment process for a PGM-group metals containing stream, said process including the steps of contacting activated carbon particles with a PGM-rich stream by contacting the stream with a batch of the particles on a continuous basis, whereby at least some of the PGM-group metals are absorbed from the stream onto active surface sites of the activated carbon and a PGM-metals depleted stream passes out of contact with the activated carbon batch, thereafter stripping the PGM-group metals from the activated carbon batch by means of a concentrated HCI solution as stripping agent, wherein the stripping agent is contacted with the activated carbon batch on a continuous flow basis and the PGM-group metals loaded stripping agent is removed from contact with the activated carbon from which the PGM-group metals have been stripped, and then regenerating the activated carbon batch by washing with water and, if necessary, reactivating the carbon particles.

L'invention concerne un procédé d'enrichissement pour un flux contenant des métaux du groupe PGM, ledit procédé comprenant les étapes consistant à mettre en contact les particules de carbone activées avec un flux riche en PGM en mettant en contact le flux avec un lot de particules sur une base continue, moyennant quoi au moins certains des métaux du groupe PGM sont absorbés à partir du flux sur les sites de surface active du carbone activé et un flux appauvri en métal PGM passe hors de contact avec le lot de carbone activé, enlevant par la suite les métaux du groupe PGM du lot de carbone activé au moyen d'une solution de HCl concentrée comme agent d'enlèvement, où l'agent d'enlèvement est mis en contact avec le lot de carbone activé sur une base d'écoulement continu et l'agent d'enlèvement chargé de métaux du groupe PGM est mis hors de contact du carbone activé duquel les métaux du groupe PGM ont été enlevés, puis à régénérer le lot de carbone activé par lavage avec de l'eau, et, si nécessaire, en réactivant les particules de carbone.
