Abstract

L'invention concerne une cathode qui est facile à installer tout en assurant une conductivité électrique. La cathode (10) est une cathode destinée à l'affinerie et est équipée d'un bloc cathodique en carbone (11), et d'au moins une barre collectrice de carbone (12), chacune étant disposée de manière à venir en contact avec le bloc cathodique (11). La surface inférieure du bloc cathodique (11) est une surface plate. La surface supérieure de chaque barre collectrice (12) est une surface plate. Le bloc cathodique (11) est disposé de sorte que la surface inférieure du bloc cathodique (11) entre en contact avec la surface supérieure de chacune des barres collectrices (12).
