The regulation of the concentration of metal ions in an electrolyte, for the electrolytic separation of metals, containing additional substances of an electrochemically reversible redox system is conventionally achieved by passing at least a part of the electrolyte through an auxiliary cell, comprising an insoluble auxiliary anode (20) and at least one auxiliary cathode (30), between which a flow of current is generated by application of a voltage. Excess amounts of the oxidised material from the redox system are thus reduced at the auxiliary cathode (30) and the formation of ions of the metal to be separated is avoided. According to the invention, pieces of the metal to be separated (30) are used as the auxiliary cathode.

Dans la technique antérieure, pour réguler la concentration d'ions métalliques dans un électrolyte servant au dépôt électrolytique de métal et contenant en outre des substances d'un système d'oxydoréduction réversible par voie électrochimique, au moins une partie de l'électrolyte est guidée à travers une cellule auxiliaire (2) présentant une anode auxiliaire insoluble (20) et au moins une cathode auxiliaire (30), entre lesquelles un flux de courant est produit par application d'une tension. Des quantités excédentaires de substances oxydées du système d'oxydoréduction sont réduites au niveau de la cathode auxiliaire (30) et, par conséquent, la formation des ions du métal à déposer est réduite. Selon l'invention, la cathode auxiliaire est constituée de fragments du métal à déposer (30).
