It is a measure of the value of copper that it is worth extracting it from such small concentrations. the ore is a mixture of minerals and rock the most common copper
copper is refined from ores in the ground, either through underground or open-pit mines. most of the copper ores mined today are oxide or sulfide ores. extraction of sulfide ores is covered in more detail in copper mining and extraction: sulfide ores but is introduced here because an important by-product of this process is used for the extraction of oxide ores.
