Copper cathodes are high-purity (99.99%) plates of copper produced through electrolytic refining or electrowinning (SX/EW). They are the primary raw material for manufacturing copper rods, wires, tubes, and alloys, characterized by excellent conductivity and low impurity levels. Standard cathodes weigh 100-250 kg, meeting LME Grade A specifications.
Key Details About Copper Cathodes
Purity & Quality: Typically
copper, ensuring high electrical conductivity, compliant with standards such as LME Grade A, ASTM B115, and DIN EN 1978.
Production Process: Produced via two main methods:
Electrowinning (SX/EW): Leaching oxide ores with acid and plating copper onto starter sheets.
Electrolytic Refining: Smelting sulfide ores into anodes, which are then refined in an electrolytic bath to produce pure cathode copper.
