most copper is mined or extracted as copper sulfides from large open pit mines in porphyry copper deposits that contain 0.4 to 1.0% copper. sites include chuquicamata, in chile, bingham canyon mine, in utah, united states, and el chino mine, in new mexico, united states. according to the british geological survey, in 05, chile was the top producer of copper with at least onethird of the world share followed by the united states, indonesia and peru. copper can also be recovered through the insitu leachproce · text under ccbysa licenseextraction copper information provided by coppermining. the ore is removed from the ground in either open pit or underground mines. undergroundcopper extraction

copper was initially recovered from sulfide ores by directly smelting the ore in a furnace. the smelters were initially located near the mines to minimize the cost of transport. this avoided the prohibitive costs of transporting the waste minerals and the sulfur and iron present in the coppercontaining minerals. however, as the concentration of copper in the ore bodies decreased, the energy costs of smelting the whole ore also became prohibitive, and it became necessary to concentrate the ores first.
initial concentration techniques included handsorting and gravity concentration. they resulted in high losses of copper. consequently, the development of the froth flotation process was a major step forward in mineral processing. it made possible the development of the giant bingham canyon mine in utah.
in the twentieth century, most ores were concentrated before smelting. smelting was initially undertaken using sinter plants and blast furnaces, or with roasters and reverberatory furnaces. roasting and reverberatory furnace smelting dominated primary copper production until the 60s.
the roasting process is generally undertaken in combination with reverberatory furnaces. in the roaster, the copper concentrate is partially oxidised to produce "calcine" and sulfur dioxide gas. the stoichiometry of the reaction which occurs is
roasting generally leaves more sulfur in the calcined product (% in the case of the roaster at mount isa mines) than a sinter plant leaves in the sintered product (about 7% in the case of the electrolytic refini · text under ccbysa licensemetallurgy of copperextraction of copperblister copperblister copper is 99% pure. it contains impurities mainly iron but little amount of as, zn, pb, ag and au may also be present. these impurities adversely affect the electrical as well as mechanical properties of copper. therefore, they must be removed.
