Abstract
For the electrolytic extraction of metal from a solution containing metal ions and situated in a first cell, metal is cathodically deposited by means of an anode on an electrically conductive endless band immersed partially into the solution, and is redissolved anodically in the electrolyte of an adjacent second cell by partial immersion of the circulating endless band; the metal dissolved in the second cell is again deposited in high purity on a cathode.
