Title

Abstract
(EN)
A contact bar and related techniques allow enhanced electrolytic refining of metals, e.g. avoiding or reducing electrical short circuits. The contact bar is adapted to rest on an insulating capping board for contacting symmetrical electrodes to provide locations for electrical contact therewith. The contact bar includes a central portion laying on the capping board and branch portions extending laterally outward from the central portion, such that the branch portions fit in between seats of the capping board. The contact bar may include a retention member enabling to reduce lateral movement of the electrodes, and may include a plurality of apertures to engage corresponding holding arms of the capping board. There may be a plurality of adjacent similar contact bar segments.

La présente invention concerne une barre de contact et des techniques apparentées permettant d'améliorer l'affinage électrolytique de métaux, par exemple d'éviter ou de réduire des courts-circuits électriques. La barre de contact est conçue pour reposer sur une carte couvrante isolante et être en contact avec des électrodes symétriques pour lesquelles elle assure des plages de contact électrique réciproque. La barre de contact comprend une partie centrale reposant sur la carte couvrante et des parties branches s'étendant latéralement depuis la partie centrale vers l'extérieur, de telle sorte qu'elles s'emboîtent entre des sièges de la carte couvrante. La barre de contact peut comprendre un élément de retenue permettant de réduire le déplacement latéral des électrodes, et une pluralité d'ouvertures pour coopérer avec des bras de retenue correspondants de la carte couvrante. Une pluralité de segments de barre de contact similaires adjacents peuvent être présents.
