Abstract

Dans le cas de l'obtention par voie électrolytique de cuivre à partir d'électrolytes contenant du cuivre et acidifié à l'acide sulfurique, on ajoute à l'électrolyte ayant une teneur en ions chlore de 150 à 200 mg/1, des ions fer en une quantité allant de 3 à 8 g/1 et on utilise une anode de plomb ayant une teneur de 2 à 4 % d'antimoine.In the case of obtaining electrolytically copper from electrolytes containing copper and acidified with sulfuric acid, ions with a chlorine ion content of 150 to 200 mg / l are added to the electrolyte iron in an amount ranging from 3 to 8 g / l and using a lead anode having a content of 2 to 4% of antimony.
