Copper is extracted in large amounts from the Earth's crust by mining of sulphide ores and also oxide ores. Studies reveal about 80% of copper is produced by its extraction from sulphide ores. Chalcopyrite is a certain kind of suphide ore that can be converted to copper by a different method from silicate, carbonate or sulphate ores.

where (E) is the processing (by extraction and milling/flotation or leaching) energy usage in MJ per kg of copper concentrate at 30%+ purity or copper in pregnant leach solution. The fixed energy cost parameter (beta) is divided by an ore grade variable (G) in percentage of copper per mass of ore extracted, so as to capture changes in energy costs.

copper mining: surface and underground mining. Due to copper being spread in relatively low concentrations over large areas, surface, or open-pit mining, is the predominant mining method for copper in the world. After mining, copper is produced by one of two process routes: pyrometallurgical or hydrometallurgical.

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).
