Extracting A Metal From Its Ore

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

Sulfide ores are more important commercially. Half of the world's copper deposits are in the form of chalcopyrite ore. Ores are removed either by open-pit or by underground mining. Ores containing as little as .15% copper can be mined profitably in open-pit mining, but underground mining is profitable only if an ore contains 6% to 7% copper.
