Titanium Solutions for Hydrometallurgy & Electroplating: Anodes, Cathodes & EquipmentTitanium Solutions for Hydrometallurgy and Electroplating Industries
The Challenge: Corrosion and Efficiency in Electrolytic Processes
The hydrometallurgy and electroplating sectors, including the production of copper, nickel, cobalt, and gold, rely on highly efficient and stable electrolytic processes. These processes involve strong acidic or corrosive electrolyte solutions, which demand materials that offer both exceptional corrosion resistance and high electrical conductivity.
Traditional materials often suffer from rapid degradation, leading to metal contamination, reduced current efficiency, and frequent equipment replacement. Titanium is the ideal material for these applications, providing a stable, long-lasting, and highly conductive substrate for anodes and cathodes.
Key Application Sectors
Our titanium solutions are critical for optimizing the following major industrial processes:
Hydrometallurgy and Gold Smelting: Equipment for leaching and recovery processes.
Electrolysis of Copper, Nickel, and Cobalt: Durable cathode starter sheets and anodes for metal refining.
Electrolytic Copper Foil Production: High-purity titanium drums and equipment for thin copper foil manufacturing.
Precious Metal Coating: Substrates for dimensionally stable anodes (DSA) with precious metal coatings.
Titanium Products and Applications
Titanium is fabricated into specialized forms to serve as the core components in electrolytic cells, ensuring maximum efficiency and minimal maintenance.

Focus on Key Grades: Detailed Corrosion Resistance and Conductivity
Grade 1 (Gr1): The purest CP titanium, offering the highest ductility and excellent corrosion resistance. It is often used for the base material of cathode starter sheets and foil lifting equipment where high purity is essential to prevent contamination.
Grade 2 (Gr2): The standard CP titanium grade, providing an optimal balance of strength, weldability, and superior corrosion resistance in most electrolyte solutions. It is the most common choice for titanium mesh substrates and general equipment.
Grade 11 (Gr11): A palladium-enhanced CP titanium alloy, offering improved crevice corrosion resistance in reducing acid environments. This is critical in areas where the anode/cathode assembly meets the busbar or other tight joints.
Grade 12 (Gr12): A titanium-nickel-molybdenum alloy, providing superior high-temperature strength and exceptional resistance to crevice corrosion. It is used in the most aggressive, high-temperature electrolytic baths where localized corrosion is a major concern.
Key Success Stories: Titanium in Hydrometallurgy
The implementation of titanium has revolutionized the efficiency and longevity of metal refining and electroplating operations globally.
Case Study 1: Enhanced Efficiency in Copper Electrowinning
Industry: Copper Electrolysis (Electrowinning)
Challenge: Traditional stainless steel cathode blanks often required frequent surface preparation and had a limited lifespan, leading to high operational costs and inconsistent copper quality.
Titanium Solution: Adoption of Grade 1 Titanium Cathode Starter Sheets. The smooth, passive surface of titanium allows for easy, clean stripping of the deposited copper, minimizing labor and maximizing the quality of the refined metal.
Outcome: Significant reduction in labor costs associated with stripping, elimination of contamination, and an increase in the purity and consistency of the final copper product, leading to a rapid return on investment.
Case Study 2: Long-Life Anodes for Precious Metal Recovery
Industry: Gold Smelting and Precious Metal Recovery
Challenge: Highly corrosive cyanide and chloride solutions used in gold recovery processes rapidly destroy conventional anode materials, requiring constant replacement and causing process interruptions.
Titanium Solution: Implementation of Titanium Mesh substrates coated with precious metal oxides (DSA). The titanium provides a stable, corrosion-proof base, while the coating ensures catalytic activity.
Outcome: The titanium-based DSA anodes achieved a service life of several years, dramatically reducing the frequency of anode replacement and maintaining stable cell voltage and current efficiency throughout the process.
