Dec 20, 2018A pre 1982 copper penny contains about 2.95 grams of copper, and there are 453.59 grams in a pound. The price of copper in December 2018 was $2.76 a pound, which makes the value of copper in each penny worth about 1.8 cents. Thus, the meltdown value of a pre 1982 penny is about 80 percent more than the face value.

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 commonest ore is chalcopyrite, CuFeS 2, a brass yellow ore that accounts for approximately 50% of the world's copper deposits. Numerous other copper ores of varying colours and compositions exist. Examples are malachite, Cu 2 CO 3 (OH) 2, a bright green ore, and the red ore cuprite, Cu 2 O. The International Centre for
