The Extraction of Copper - Chemistry LibreTexts

Copper(II) ions are deposited as copper on the cathode (for the electrode equation, see under the purification of copper below). The anodes for this process were traditionally lead-based alloys, but newer methods use titanium or stainless steel. The cathode is either a strip of very pure copper which the new copper plates on to, or stainless steel which it has to be removed from later.

Extraction et métallurgie - European Copper Institute

Le cuivre n'est présent dans l'écorce terrestre qu'à la concentration moyenne de 55 parties par million. II n'existe plus dans la nature à l'état natif, comme dans l'antiquité. II se présente sous forme de sels contenant 30 à 90 % de cuivre, eux-mêmes mélangés aux stériles et quelquefois à d'autres métaux, dont certains peuvent être plus rares que le cuivre, comme l'or et l'argent.

Extraction Of Copper | Mining, Concentration, …

Copper Mining: The commonest ore used in the extraction of copper is Chalcopyrite (CuFeS 2) also known as Copper Pyrites and other such sulfides. The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The concentration of ore is required and it is done by the Froth Flotation method. Concentration of Ore:
