NEET UG : Extraction of Copper, chemistry
Chalcopyrite (also known as copper pyrite) and other sulfide ores are the most popular ores used in the copper extraction process. There is a requirement for the concentration of ores with a low percentage of Copper before they can be refined for the final extraction of Copper. Extraction of Copper is generally through the self-reduction method.
