Extracting metals from rocks

28 · Malachite is a copper ore consisting mainly of basic copper(II) carbonate, CuCO 3.Cu(OH) 2. This experiment involves producing copper from copper(II) carbonate. The copper carbonate is first heated to produce copper(II) oxide, which is then reduced to the metal using carbon as a reducing agent.
