Copper - Compounds, Properties, Uses: Copper forms compounds in the oxidation states +1 and +2 in its normal chemistry, although under special circumstances some compounds of trivalent copper can be prepared. It has been shown that trivalent copper survives no more than a few seconds in an aqueous solution. Copper(I) (cuprous) compounds are all diamagnetic …

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

Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.

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.
