Encyclopedia of Electrolytic Copper Anode Plate: Foundation for High-Purity Copper Refining
2026-05-26
I. Product Overview
The electrolytic copper anode plate is a crude copper plate used for electrolytic refining in the copper smelting industry. It purifies crude copper (purity approx. 98.5%-99.5%) produced by pyrometallurgy to produce standard cathode copper with a purity of over 99.99%.
II. Manufacturing Standards
High-quality electrolytic copper anode plates must meet strict physical and chemical requirements:
- Composition Control: Copper content is usually not less than 98.5%, strictly controlling harmful impurities like arsenic, antimony, and bismuth to prevent suspended anode slime during electrolysis.
- Dimensional Accuracy: High flatness ensures uniform electrode spacing, avoiding local high current density that causes short circuits or burning plates.
- Surface Quality: Smooth and dense surface without pores, cracks, or severe oxidation extends the electrolysis cycle.
III. Process Flow
Production typically involves anode furnace refining, disc casting, and trimming. The application of modern continuous casting and rolling technology significantly improves internal density and dimensional consistency.
IV. Industry Applications
Mainly used in electrolytic refining workshops of copper smelters, it is an essential link for high-end manufacturing industries like wires/cables, electronics, and aerospace to obtain high-purity copper materials.
