Extracting a metal from its ore
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

The new gold colored coin is made up of 90% copper. The penny contains only 2.6% copper. In 1982, the U.S. Mint converted production of the 95% copper coin to a predominantly zinc alloy, but coated it with copper to preserve its appearance. The U.S. nickel is actually 75% copper. The dime, quarter, and half dollar contain 91.7% copper.
