MMO Coated Titanium Anode for Cylindrical Electrowinning Cell

MMO Coated Titanium Anode for Cylindrical Electrowinning Cell

Traditional electro winning cells design with the planar electrode, current efficiencies plummet once the concentration of the electro won metal in solution decreases. Due to inadequate mixing, depletions forms around the cathode and at low concentrations, hydrogen evolution occurs and other unwanted materials are electrodeposited and the morphology of electrodeposited metal changes. This compromises both the efficiency and selectivity of the electro winning process.

Cylindrical cells adopts an anode mounted in the center of a cylindrical cathode, they are  featured for a high flow rate to enhance the rate of mass transfer, overcoming issues associated with depletion zones and enabling the production of high-purity metals even in the presence of impurities.

The anode material is significant for an electrowinning cell, some anodes have a low oxygen evolution potential so that the cell voltage is significantly reduced. Traditional lead anodes encounter drawbacks of lead sludge build-up, more labor cost due to its heavyweight in operation, and health and safety risk.

UTron designed a novel Nano-Oxide coated titanium anode, which is proven to increasing the current efficiency and the capacity of the existing electrolytic plants; This MMO coated titanium anode can reduce the oxygen evolution potential by 0.5 V compared to lead alloy anodes, improving morphology of the cathodic metal deposit. It is of high corrosion stability and high cathodic activity.
