Extracting Copper from Malachite - GCSE Science - Marked ...
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.

2020-12-16 · Dec 15, 2020. #2. Hi You need to reduce the malachite first to copper oxide on a fierce flame. It will go black, then you add the carbon and heat for about 20 -30 mins. I have never had solid copper metal but you should bet semi solid copper powder. It helps if you can use small chunks of malachite too as it will reduce quicker and easier.

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
