Copper Mining and Extraction Sulfide Ores

Stage 3: Roasting At this stage of the process, the chemical reactions begin. They convert the copper minerals into copper metal. We can illustrate the types of process using the example of chalcopyrite – CuFeS 2.From the formula, it is clear that iron and sulfur have to be removed in order to produce copper.

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 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 ...
