Malachite is a copper ore consisting mainly of basic copper(II) carbonate, (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. If possible, show the class a genuine sample of malachite ore and artefacts, such as paperweights or polished ...

Malachite: Uses and properties of the mineral and gemstone

Malachite is a green copper carbonate hydroxide mineral with a chemical composition of Cu 2 (CO 3 ) (OH) 2. It was one of the first ores used to produce copper metal. It is of minor importance today as an ore of copper because it is usually found in small quantities and can be sold for higher prices for other types of use.

 · Mechanical activation (MA) of malachite was carried out by dry planetary grinding (DPG) and wet Isa grinding (WIG) methods. When the rotational speed was increased to 400 r/min in DPG, the specific surface area of malachite reached the maximum and the particle size reached the minimum of –100 μm. Agglomeration occurred between mineral particles when the rotational speed was increased to ...

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

Malachite [Cu 2 (OH) 2 CO 3; green copper ore] and azurite [Cu 3 (OH) 2 (CO 3) 2; blue carbonite copper] are other ores of importance. In addition, crude phosphates used in the production of phosphate fertilizers may contain significant amounts of copper. Sulfidic ores often contain naturally high concentrations of arsenic (Barceloux, 1999).
