Abstract: An electrode for electrolytic processes, in particular to an anode suitable for oxygen evolution having a valve metal substrate, a catalytic layer, a protection layer consisting of oxides of valve metals interposed between the substrate and the catalytic layer and an outer coating of oxides of valve metals. The electrode is particularly suitable for processes of cathodic electrodeposition of chromium from an aqueous solution containing Cr (III).

Abstract: The invention relates to a cell for metal electrowinning equipped with a device useful for preventing the adverse effects of dendrite growth on the cathodic deposit. The cell comprises a porous conductive screen, positioned between the anode and the cathode, capable of stopping the growth of dendrites and avoiding that they reach the anode surface.
