Titanium anodes, also known as Dimensionally Stable Anodes (DSA) or Mixed Metal Oxide (MMO) anodes, offer unparalleled performance in the harsh conditions of high-chlorine, strong-acid etching solutions:
- Exceptional Corrosion Resistance: Titanium forms a protective passive oxide film that resists attack from chloride ions, hydrochloric acid, and chlorine gas
- Dimensional Stability: Unlike graphite or lead anodes, titanium anodes maintain their shape and electrode gap throughout their service life
- High Current Efficiency: Noble metal oxide coatings significantly reduce reaction overpotentials, improving energy efficiency
- No Secondary Pollution: Titanium anodes do not dissolve into the electrolyte, preventing contamination of the recovered copper
- Reusable Substrate: The titanium base can be recoated multiple times, reducing long-term costs
