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 2-3%.

Copper extraction - Academic Kids
Jun 18, 2005 Currently, the most common source of copper ore is the mineral chalcopyrite (CuFeS 2), which accounts for about 50% of copper production.The focus of this article is on the process of copper extraction from chalcopyrite ore into pure metal. Processes for other minerals are mentioned. For economic and environmental reasons, many of the byproducts of extraction are reclaimed.
