Although fire-refined copper reaches a copper content of 99.9%, impurities such as Ni, Fe, As, Sb, and Bi cannot be removed. Electrolytic refining leverages differences in electrochemical potential to produce high-purity cathode copper (99.99%), meeting the demands of high-end sectors such as cables, copper foil, and semiconductors.

Discover how high-purity electrolytic copper is made through anode casting, electrolyte purification, and precise electrolysis operation.

What is the core objective of copper electrolytic refining, and how does the equipment achieve this objective?

Its importance is reflected in several aspects.

In antimony electrolysis equipment, how can the cathodic antimony be prevented from being contaminated by anode slime?

In electrolytic antimony equipment, how can the purity and physical morphology of the cathodic antimony be controlled?
