Abstract

L'invention concerne un procédé électrochimique à faible corrosion destiné à préparer du zinc métal, consistant à réaliser une réduction électrochimique d'une solution aqueuse basique de zinc ou d'une suspension d'oxyde de zinc ou de tout composé de zinc réagissant avec une base aqueuse afin de donner de l'oxyde de zinc, ce procédé électrochimique étant mené dans une cellule électrochimique non divisée dans laquelle de l'air ou de l'azote est passé, sous forme de bulles, à travers la solution ou la suspension d'oxyde de zinc ou d'autre composé de zinc, durant le procédé électrochimique.
