    DSA-anodes are widely used in metal electrowinning. In zinc electrowinning the electrolyte solution contains manganese ions, and the deposition of manganese dioxide happens on the anode. This manganese dioxide layer cannot be removed without losing the active coating of the DSA-anode. The same problem can be found with hybrid anodes. In hybrid anodes mixed metal oxide coated titanium mesh is attached to a lead base material. In this study, the effect of dissolved manganese on anode behaviour is studied with three different anodes. These anodes are lead anode with 0.6% silver, hybrid anode and DSA-mesh. Methods of study include polarization, galvanostatic and potential mapping experiments.
