Brass, a copper-zinc alloy, was used by the Romans for coinage during the reign of Augustus 27 BCE-ACE14. Today copper plays a major role in our technological society. It is used in electronic circuitry, construction, cookware, piping, coinage, and wiring. When left unprotected from atmospheric oxygen, it forms a green oxide, CuO, commonly seen on the rooftops of …

Copper can be extracted from its ores by reduction. One of the common copper ores, malachite, which is composed of mainly copper carbonate, CuCO3xCu(OH)2, is heated to produce copper oxide with the release of carbon dioxide. CuCO3xCu(OH)2 → 2 CuO + CO2 + H2O The copper oxide is then heated with carbon to get copper. 2 CuO + C → 2 Cu + CO2
