Copper

The core products of KGHM are electrolytic copper cathodes with minimum 99.99% of copper content. The company processes ore to obtain concentrate and metallic copper in the form of wire rod, Cu-OFE and Cu-Ag wire, round billets and granules.

The main source of copper produced by KGHM are mines solely owned by the company.  The exception is Sierra Gorda mine in Chile, which is now at the commissioning stage, where KGHM owns 55% of shares.  The remaining mines are located in Poland (Lubin, Rudna, Polkowice-Sieroszowice), Chile (Franke, Sierra Gorda), Canada (McCreedy, Morrison) and the USA (Carlota, Robinson). Over 30 ml Mg of unrefined material is extracted annually. With an average ore grade of 1.6% copper, KGHM produces approximately 700 thousand tonnes of red metal.

The core products of KGHM are electrolytic copper cathodes with minimum 99.99% of copper content. What is more, the company processes ore to obtain concentrate and metallic copper in the form of wire rod, Cu-OFE and Cu-Ag wire, round billets and granules.

Most of KGHM’s production is sold on the basis of long-term contracts (typically annual contracts or longer), with the balance sold under short-term or “spot”agreements.

Wire Rod

KGHM Polska Miedź S.A. "Cedynia" Copper Smelter Branch produces copper wire rod of 8 mm ± 0.4 mm and 10 mm ± 0.4 mm diameters under the continuous melting, casting and rolling method.

The surface of the wire rod is cleaned by the alcohol method and coated with a synthetic wax layer which protects the surface against oxidation during transport and storage.

The wire rod has a uniform microstructure, with uniform oxygen distribution. Oxygen content is low enough to ensure good drawability and a low recrystallisation temperature.

The "Cedynia" Copper Smelter Branch of KGHM Polska Miedz S.A. holds a quality certificate conforming to PN-EN ISO 9001:2001, PN-EN ISO 14001:2005 and PN-N 18001:2004 issued by the Polish Research and Certification Centre, which covers the production of copper wire rod.

Cu-OFE Wire

"Cedynia" Copper Smelter Branch of KGHM Polska Miedź S.A in Orsk produces the oxygen-free copper wire under UPCAST technology. The installation was commissioned in 2006 thus increasing the production capacity of the plant by 15 K tonnes per year. UPCAST technology enables the production of wire of various diameters (8-12, 7-16-20-22-24-25 mm) and of wire from low-alloy copper with the addition of silver. This installation includes a cathode charging system, an induction melting furnace, an induction casting furnace, a casting machine with moulds and primary and secondary coolers for vertical casting along with 16 coiling machines.

  • for extruding:

Cu-OFE wire is an ideal material for continuous flat or round extruding using the Conform® process.

  • for rolling:

Cu-OFE wire may also be rolled into flat or round sections. .

Benefits of using Cu-OFE wire:

  • Production from selected cathodes,
  • The surface has a light metallic colour, free of flakes,
  • No intrusions from the rolling process,
  • Uniform product quality,
  • Thin diameter tolerance,
  • Resistant to hydrogen embrittlement.

Quality requirements for cathodes:

  • Cu CATH-1 (cathodes LME A-grade),
  • Selected with lowest content of impurities,
  • Clean surface of the cathodes - rinsing,
