![]() While the copper(II) oxide produced by heating cools down, discuss how to get the oxygen out of the oxide, leaving the metal itself. This forms the first part of the experiment. ![]() It contains copper, but how can copper metal be obtained from it? Heating will probably be suggested. If possible, show the class a genuine sample of malachite ore and artefacts, such as paperweights or polished ‘eggs’ made from malachite, noting the green colour characteristic of many copper compounds. 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. Malachite is a copper ore consisting mainly of basic copper(II) carbonate, CuCO3.Cu(OH)2.
