A method for the production of metallic copper in a substantially dendrite-free crystalline form is described, comprising an electrowinning from a cuprous and/or cupric chloride solution carried out in a spouted bed cell comprising a cathode consisting of a descending bed of metallic beads.

Method for copper electrowinning in hydrochloric solution

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from metal ion solutions is described, wherein the cathode () consists of a falling bed of growing beads; the beads, withdrawn from the lower part of the bed, are recycled to the top section of the cathodic compartment by means of an external vertical duct ().

Falling bed cathode cell for metal electrowinning

It is herein described an electrowinning cell with a spouted bed electrode of growing metallic beads, separated by a semi-permeable diaphragm and suitable for being assembled in a stack in a modular arrangement.
