Copper ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.

WhatsAppGet PriceGet A QuoteThe process for extracting copper from copper oxide ores can be summarized as: Mining : digging or blasting to obtain the ore from the surrounding rock. Crushing : mined ore is crushed into very small pieces. Grinding : crushed ore is ground into a powder. Concentrating : adding water to the powder to create a slurry containing about 15% copper

WhatsAppGet PriceGet A QuoteCopper 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
