The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ( C u F e S 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.

Copper mining. From ore to copper. - School Science
What's in an ore? There are many types of copper ore found throughout the world. Picture 4 shows the distribution of these deposits. About 80% of all copper extracted comes from sulphide ores. A typical ore contains only 0.5% to 2.0% copper. It is a measure of the value of copper that it is worth extracting it from such small.
Copper extraction - Wikipedia

Copper Mining and Processing: Processing of Copper Ores .
Since each mine site is unique in its mineral composition, concentration, and quantities, the most economical and profitable processing of ore must be determined by the mine planners. When it is economically feasible, a mine may extract both types of copper minerals; when it is not possible, mines will only process either.
