Abstract
It is described an electrolysis cell wherein the anodic dissolution of metals is carried out, in particular of metals characterised by a relatively high oxidation potential, such as copper, or metals with high hydrogen overpotential, for example tin, aimed at restoring both the concentration of said metals, and the pH in galvanic baths used in electroplating processes with insoluble anodes. The cell of the invention comprises an anodic compartment, wherein the metal to be dissolved acts as a consumable anode, and a cathodic compartment, containing a cathode for hydrogen evolution, separated by a cation-exchange membrane. The coupling of the cell of the invention with the electroplating cell allows a strong simplification of the overall process and a sensible reduction in the relevant costs.
