Copper extraction - Wikipedia

The average grade of copper ores in the 21st century is below 0.6% copper, with a proportion of economic ore minerals being less than 2% of the total volume of the ore rock. Thus, all mining operations, the ore must usually be beneficiated (concentrated). The concentrate is typically sold to distant smelters, although some large mines have smelters located nearby. Such colocation of

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

Copper Metal from Malachite circa 4000 B.C.E.

Around 6000 years ago the procedure involved heating copper ore in the presence of charcoal; we have created a laboratory experiment inspired by this idea. The experiment starts with a naturally occurring ore, malachite, essentially pure Cu 2 CO 3 (OH) 2, which is readily available at modest cost in bead form from jewelry stores.
