Extracting copper from copper(II) carbonate Experiment

Malachite is a copper ore consisting mainly of basic copper(II) carbonate CuCO3.Cu(OH)2. In this experiment students learn how to produce copper from copper(II) carbonate by heating it to produce copper(II) oxide which is then reduced to the metal using carbon as a reducing agent.

Prospecting from OrbitNASA Earth Observatory

Like most metals copper doesn t exist in abundance on the Earth s surface. In fact copper only makes up 0.00007 percent of the Earth s crust. So even in areas where deposits are common copper is not easy to spot. "What we do is look for other minerals that generally indicate that copper is

How copper is madematerial used processing steps

Most of the copper used before 4000 B.C. came from the random discovery of isolated outcroppings of native copper or from meteorites that had impacted Earth. The first mention of the systematic extraction of copper ore comes from about 3800 B.C. when an Egyptian reference describes mining operations on the Sinai Peninsula.

Copper production environmental impact

• Recycling a tonne of copper uses 20 of the energy that would be used to mine and extract the same copper. • The copper recycling process has much in common as that to extract it but requires fewer steps. High-purity copper is melted in a furnace and then reduced Low-purity copper is refined through electroplating in sulfuric acid.
