2020-12-16  labmom. 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.

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
