KGHM owns three copper smelters:
- "Cedynia" - rolling mill
They are all located in Poland, in the Lower-Silesia region. Their production capacity amounts to 540 thousand tonnes of electrolytic copper and 1200 tonnes of silver a year.
These values place KGHM's smelting potential among the largest producers in the world.
The production in the KGHM smelters mainly relies on the company's own resources and copper ore concentrates produced on-site. KGHM's processing strategy is based on maintaining production scale at the level of 500 thousand tonnes of electrolytic copper with a simultaneous increase in mining efficiency in all the mines in the world. The company plans to boost the recovery of elements from copper production and continuously improve metallurgical technologies.
The technological processes in all three KGHM's smelters are based on different solutions.
In the "Głogów" smelter, the copper is smelted in a flash furnace technology - the first such innovative installation in the world. The smelter, in its structure, also includes Precious Metals Plant that produces silver and gold.
The "Legnica" smelter produces copper cathodes by means of traditional technology of the shaft furnace and through the process of electro-refining.
The "Cedynia" smelter is a copper rolling mill that processes electrolytic copper produced in the other two smelters, 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 smelters also produce:
- refined lead
- sulphuric acid
- nickel sulphate
