Abstract

1. Method for electrolytically separating metals from aqueous solutions of metal salts on a steel band, using high relative flow velocities between the electrolyte and the steel band, as well as anodes for achieving greater current densities at the lowest possible energy consumption, wherein a stream of electrolyte is passed parallel to the band surface from one of the ends of the electrolysis cell, in or against the direction of movement of the band, and wherein strong relative flow is obtained by subjecting the stream of electrolyte, directed along the plane of the steel band, to a turbulent state of flow, by partial streams of electrolyte from nozzles, arranged laterally of the edges of the band and spraying transversely of the direction of movement of the band and parallel to the band surface or in the direction towards the edges of the band.
