Cathodes in Hydrometallurgy: Key Components for Copper and Zinc Refinement
Cathodes are essential devices in hydrometallurgy, utilized for refining copper, zinc, and other metals through electrolysis or electrowinning processes. The cathode plates used for refining copper and zinc are typically constructed from 316L stainless steel, while the cathode hanger bars are made from refined copper. Stainless steel cathodes are often referred to as permanent cathodes due to their durability and longevity.
Recently, aluminum alloys have been adopted for the production of cathodes used in zinc refinement. These aluminum cathodes, known as Al cathodes, offer unique advantages in the electrowinning process.
The machining processes for stainless steel cathodes are carried out using advanced automatic or CNC machining equipment, ensuring precision and high-quality manufacturing standards.

FAQ
Q: What payment terms do you accept?
A: We accept Letter of Credit (LC), Telegraphic Transfer (TT), and cash payments to accommodate our clients' needs.
Q: Do you offer installation services?
A: Yes, we provide installation services and detailed online instructions based on client requirements.
Q: Can you provide design services?
A: Yes, we offer customized design services and tailored cathode solutions to meet client specifications.
Q: What are the raw materials and final products of the electrolytic cell?
A: Our electrolytic cells use copper sulfate (CuSO₄) and zinc sulfate (ZnSO₄) as raw materials, producing refined copper (≥99.99% Cu) and refined zinc (≥99.99% Zn).
Q: Can the cathode operate independently?
A: No, the cathode must work with the electrolytic cell, anode, busbar, and other components for effective metal refining.
