The Extraction of Copper

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. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper.

Copper Mining and Extraction: Sulfide Ores (11-14)

Place these products in the extraction process in ascending order of copper content.
