Aug 21, 2020 copper is much rarer, but fortunately can be found in high-grade ores (ones containing a high percentage of copper) in particular places.Because copper is a valuable metal, it is also worth extracting it from low-grade ores as well.Ores are commonly oxides, for example: bauxite (al 2 o 3) haematite (fe 2 o 3) rutile (tio 2).

Aug 21, 2020 sulfide ores such as chalcopyrite (\(cufes_2\)) are converted to copper by a different method from silicate, carbonate or sulfate ores.Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.The ores typically contain low percentages of copper and have to be concentrated before refining (e.
