Copper

Pure copper occurs rarely in nature. Usually copper found in such minerals as azurite, malachite and bornite and in sulfides as in chalcopyrite (CuFeS2), covellite (CuS), chalcocite (Cu2S) or oxides like cuprite (Cu2O). Copper is obtained by smelting, leaching and by electrolysis.

Most often used as an electrical conductor. Its alloys are used in jewelry, bronze sculptures and for coins. The skin of the Statue of Liberty is made of copper.

Copper is a very interesting element used in open-pit mines in plumbing, electrical wires, and coins; Component of alloys. It is one of the transition elements that actually use electrons from one of the inner orbitals in chemical reactions. In addition, it has more than one oxidation state. Brass and bronze are alloys of copper.
