Abstract
An electrolytic cell and process are described for use in a plant for the cathodic recovery of a metal from, for example, an ore. The cell includes one or more intermediate compartments which are bounded by ion-permeable separators and are disposed between the anode compartment and the cathode compartment. In the process, an aqueous solution of a salt of the metal is circulated around a first circuit including the cathode compartment of the cell, and an acid solution is circulated around a second circuit including the anode compartment. The fluid in the intermediate compartment(s) may also be circulated.
