What is a Copper Cathode?
The cathode is the basic product of copper production. It is produced in a marketable form at Aurubis for use in high-quality applications.
A cathode – a 50 to 80 kg copper square – is produced when pure copper separates from unwrought copper in an electrolytic refining process.

Who makes copper cathodes?
It is produced in a marketable form at Aurubis for use in high-quality applications. Aurubis cathodes are produced with ISA Technology and comply with the cathode standards LME Grade A, Cu-CATH-1 (EN 1978) and Copper Cathodes Grade 1 (ASTM B115).
How are copper cathodes shipped?
Electrolytic copper cathodes are usually bought upon a weight basis, and are normally shipped unpacked, often bound together with metal bands.
Is copper cathode a raw material?
At Rio Tinto Kennecott (RTK), we take pride in responsibly producing copper cathode, a primary raw material used in the production of semi-fabricated products such as copper wirerods for the wire and cable industry.
Why pure copper is used as a cathode?
This process is called electrolysis. We want the pure copper to be collected on the cathode electrode where we can retrieve it easily and the impurities to be left behind in the sludge.
The copper is attracted to the anode to equalize the electrical charges. The impurities are NOT attracted to the cathode.
