Extracting a metal from its ore - chymist

2006-6-27 · 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

Watch an experiment to extract copper from copper ore. Refining iron. The iron that is formed in the blast furnace often contains too much carbon - about 4% where it should contain not more than 2%. Too much carbon makes the iron brittle. To improve the quality of the iron, it needs to be refined by lowering the amount of carbon.

Copper Dendrite - MEL Chemistry

Why does this copper dendrite look completely different from other copper items, including the rings in the Alchemy experiment from this set? When exposed to atmospheric oxygen O 2, copper Cu is oxidized – it reacts with oxygen to form black copper(II) oxide CuO.As a result, the surface of any copper object is covered with a thin black film that protects it from further oxygen attacks.
