Electrolytic extraction of metals uses an insoluble anode to reduce the metal ions to be extracted in the electrolyte that has been leached and purified at the cathode to obtain pure metals. The biggest difficulty in electrolytic extraction of metals is the selection of suitable anode materials. The anode requires stability, corrosion resistance, and can be used for a long time. The anode process has good electrocatalytic activity to reduce the overvoltage and bath voltage of the anode reaction. Electrolytic extraction of metals requires the use of anode stability, corrosion resistance, and good electrocatalytic activity for the anode process to reduce the overvoltage and bath voltage of the anode reaction. In recent years, coated titanium electrodes have been widely used in the field of electrolytic extraction of metals. After extensive research and testing, it has been shown that the coated titanium anodes produced by our company can not only obtain high-purity products, but also have a long service life and good electrocatalytic activity.
