    Chemistry Extracting Copper from Malachite We extracted Copper from Malachite using a displacement reaction. Although electrolysis can also be used. We used 5g of malachite and dissolved it in sulphuric acid; this was to separate the sand and the copper, because the copper dissolves into the solution but the sand remains separate.

    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

    Malachite is a fairly hard rock, but copper oxide is very soft and crumbly. This is because it gets broken up as the carbon dioxide comes out of it. As the rocks crumbled, more of the copper oxide would have been moved into the middle of the fire where it got hotter. Add the copper oxide to the beaker and add the carbon.
