In the metal electrowinning process, metal ions in the electrolyte are reduced and deposited on the cathode, while at the anode, water is decomposed to release oxygen. The reaction at the titanium anode is usually: 2H2O → O2 + 4H+ + 4e-. Titanium anodes act as insoluble anodes, providing a stable current path, ensuring uniform current distribution, and facilitating the smooth progress of the electrolysis reaction.According to different coating materials, titanium anodes for metal electrowinning mainly include iridium – tantalum oxide – coated titanium anodes, ruthenium – iridium oxide – coated titanium anodes, etc. These coatings have excellent electrocatalytic activity and corrosion resistance, which can meet the requirements of different metal electrowinning processes.
Advantages of Titanium Anodes
High Corrosion Resistance: Titanium has good corrosion resistance in various acidic and alkaline electrolytes. For example, in the sulfuric acid – based electrolyte used in copper electrowinning, titanium anodes can maintain stable performance without being corroded, ensuring a long service life.
Low Energy Consumption: The metal oxide coating on the surface of titanium anodes has a low over – potential for oxygen evolution, which can reduce the working voltage of the anode and thus save electrical energy. Generally, the direct current consumption of titanium anodes can be reduced by 10% – 20% compared with other anodes.
High Current Efficiency: Titanium anodes can provide uniform current distribution, enabling efficient deposition of metals on the cathode. In copper electrowinning, using titanium anodes can increase current efficiency by 18%, and improve the purity of cathode copper from 99.95% to 99.997%.
Stable Performance: During the electrolysis process, the size of titanium anodes remains stable, and the distance between electrodes does not change, which can ensure the stability of electrolysis operation and the consistency of product quality.
Environment – Friendly: Compared with traditional lead – based anodes, titanium anodes do not produce heavy – metal pollution, which is beneficial to environmental protection. For example, using titanium anodes can reduce heavy – metal pollution emissions by 90%.
Titanium anodes are widely used in the electrowinning of non – ferrous metals such as copper, nickel, cobalt, and zinc. In copper electrowinning plants, titanium anodes can improve the quality of cathode copper and reduce production costs. In nickel and cobalt electrowinning, due to the strong corrosiveness of the electrolyte, titanium anodes with appropriate coatings are also the first – choice materials.

production
1. Substrate treatment: it needs to be treated by roughing, cleaning and removing oil, which can increase the compactness of catalytic.
2. Brushing coating:After substrate treatment, it will be proceeded brush coated. The main coated content is platinum group metal, which is a kind of mixed solution.Then, heat treatment will be going on after drying.The whole procedure need to be repeated many times. This method is better to form thin oxide catalytic that is lamellar adhere to substrate surface.
