The Extraction of Copper - Chemistry LibreTexts

The method used to extract copper from its ores depends on the nature of the ore. 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 conta low percentages of copper and have to be concentrated before refg (e.g., via froth flotation).

Copper extraction - Wikipedia

Copper ores contag chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% copper--concentrate (usually 27–29% copper); the remader of the concentrate is iron and sulfur the chalcopyrite, and unwanted impurities such as silicate gangue merals or other sulfide merals, typically mor amounts of pyrite, sphalerite or galena.
