Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated (concentrated). The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as chalcopyrite), th

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 of Metals. The History of Metals. Metals have been used by people for many thousands of years. Gold and silver, found as native metal, were used both as jewellery and as a status symbol - nothing new there. These metals were known in the Stone Age but gold and silver are too soft to be used as tools. The first really useful metal to be discovered was bronze. This began the Bronze ...
