Abstract

L'invention concerne une électrode à flux traversant tridimensionnelle comprenant un mécanisme d'alimentation par courant efficace, des conduits d'alimentation comprenant des tiges en matière conductrice, notamment le graphite, qui sont insérées à des intervalles spatiaux prédéterminés dans une électrode à flux traversant, notamment un bloc de feutre de graphite. Les conduits d'alimentation de courant sont espacés de manière appropriée à travers l'électrode pour permettre une distribution efficace du courant. La grande zone de surface dotée de l'électrode à flux circulant permet d'exposer des solutions ou des gaz sur des zones relativement grandes de charges électriques, pour provoquer des réactions électriques et chimiques. Un certain nombre de procédés chimiques électrolytiques faisant appel à des cellules électrolytiques comprennent le traitement de l'eau, le traitement chimique et la production chimique, des applications hydrométallurgiques et un nettoyage écologique. L'invention concerne une méthode de remplacement de l'utilisation de cyanure dans des opérations de traitement d'or et d'argent.
