Abstract

L'invention concerne l'industrie de l'électrolyse. Extraction électrolytique de nickel d'un électrolyte dans une cellule comportant une cathode insoluble et une anode insoluble, celle-ci étant caractérisée en ce qu'elle comporte un substrat de titane, zirconium ou tantale, qui porte successivement un voile d'un métal du groupe du platine et une couche de bioxyde de plomb, l'électrolyte étant caractérisé en ce qu'il contient en solution, outre le nickel, un composé de manganèse en une quantité correspondant à au moins 0,1 g/l de manganèse. Le bioxyde de manganèse qui se forme à l'anode inhibe la dissolution du plomb de l'anode et la contamination par le plomb du dépôt de nickel électrolytique.The invention relates to the electrolysis industry. Electrolytic extraction of nickel from an electrolyte in a cell comprising an insoluble cathode and an insoluble anode, the latter being characterized in that it comprises a substrate of titanium, zirconium or tantalum, which successively carries a veil of a metal from platinum group and a layer of lead dioxide, the electrolyte being characterized in that it contains in solution, in addition to nickel, a manganese compound in an amount corresponding to at least 0.1 g / l of manganese. The manganese dioxide that forms at the anode inhibits the dissolution of lead from the anode and the lead contamination of the electrolytic nickel deposit.
