    Sulfide ores such as chalcopyrite CuFeS2 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.g. via
