KGHM owns three copper metallurgical facilities:
- The Głogów Copper Smelter and Refinery
- The Legnica Copper Smelter and Refinery
- The Cedynia Wire Rod Plant
These production facilities are all located in Poland, in the Lower-Silesia region.
Production by KGHM’s smelter/refineries mainly relies on the geological company's own resources and copper ore concentrates produced on-site. KGHM's current processing strategy is based on maintaining production at the average level of 540 thousand tonnes of electrolytic copper in the period 2019-2023 with a simultaneous increase in mining efficiency in all of the Company’s mines globally. The company plans to boost the recovery of elements from copper production and continuously improve metallurgical technologies.
The technological processes in all three of KGHM's metallurgical facilities are based on different solutions.
In the Głogów Copper Smelter and Refinery, copper concentrate is smelted using flash furnace technology. This facility also includes a Precious Metals Plant that produces silver and gold.
The Legnica Copper Smelter and Refinery produces copper cathodes by means of traditional shaft furnace technology of the shaft furnace and through the process of electrorefining. Recently a new copper scrap casting furnace wad added to Legnica’s production line.
The Cedynia Wire Rod Plant is a copper rolling mill that processes electrolytic copper produced in the smelter/refineries, Głogów and Legnica. Production is carried out with a modern installation for the production of wire rod using the Contirod method, without the use of billets. Also, copper wire Upcast is produced.
Apart from copper, silver and gold, KGHM's metallurgical facilities also produce:
- refined lead
- sulphuric acid
- nickel sulphate
