Electrowinning is an electrolytic process that deposits high purity metal on the cathode by applying external electrical. In the electrowinning process, metal reduction and reaction occur on the cathode, and water is decomposed at the anode surface to release oxygen. Core components Titanium Anode of Electrowinning coated with iridium tantalum, ruthenium iridium in mesh or plate shape Which has a good acid and alkali corrosion resistance,long service life and high electrocatalytic activity.
