Copper can be extracted from non-sulphide ores by a different process involving three separate stages: Reaction of the ore over quite a long time and on a huge scale with a acid such as sulphuric acid to produce a very dilute copperII sulphate solution.

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. 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 …
