copper extraction and purification - chemguide
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 Extraction of Copper - Chemistry LibreTexts
The Process. The concentrated ore is heated strongly with silicon dioxide (silica) and air or oxygen in a furnace or series of furnaces. The copper(II) ions in the chalcopyrite are reduced to copper(I) sulfide (which is reduced further to copper metal in the final stage). The iron in the chalcopyrite ends up converted into an iron(II) silicate slag which is removed. Most of the sulfur in the ...

Leaching of cuprite through NH4OH in basic …
Therefore, to treat this copper oxide (cuprite), an oxidant capable of leaching the cuprite should be used to achieve extraction rate above 50% Cu. An attractive and alternative process is the use of aqueous ammoniacal solutions. Several studies have been performed by using this process to treat oxidized copper minerals [3−7]. However, there is a current process in which the dissolution ...
