ABSTRACT:
A cell (100) for metal electrowinning from metal ion solutions is described, wherein the cathode (1) consists of a falling bed of growing beads; the beads, withdrawn from the lower part of the bed, are recycled to the top section of the cathodic compartment by means of an external vertical duct (3).
