Copper Price, Occurrence, Extraction and Use Institute

Process of copper extraction. For the production of copper, so-called copper stone (Cu2S with varying contents of FeS, Cu content approx. 2%) is first obtained from chalcopyrite (CuFeS70). For this purpose, the starting material is roasted with the addition of coke and the contained iron oxides slagged by siliceous aggregates.
