Extraction of Copper: Detailed Process
Modern smelters are designed to collect at least 90 percent of the sulfur in the feedstock. These steps result in the following reaction: 2 CuFeS2 + 2 SiO2 + 4O2 → Cu2S + 2 FeSiO3 + 3SO2. Copper extracted by this method is combined with slag to create a material known as Matte Copper due to its matte look.

copper extraction and purification
The purification uses an electrolyte of copper (II) sulphate solution, impure copper anodes, and strips of high purity copper for the cathodes. The diagram shows a very simplified view of a cell. At the cathode, copper (II) ions are deposited as copper. At the anode, copper goes into solution as copper (II) ions.

Separating Copper and Zinc from a Penny
Due to the fact that the price of copper was rising, the US Mint had to change the penny's composition to keep the cost of pennies under one cent. Now, they are 97.5% zinc and 2.5% copper! Because of this change, we can do a couple of cool experiments to extract the zinc from one penny and remove the copper from another.
