extraction of copper from chalcopyrite

Why the Extraction of Copper from Chalcopyrite is so

Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate, carbonate or sulphate ores So, extraction of Copper from it becomes very difficult & it is a lengthy process because(i) It contains many impurities in such a high amount that the percentage of Copper in it becomes only 23%
