Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper ores consists of a series of physical, chemical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.

The Bingham Canyon Mine, more commonly known as Kennecott Copper Mine among locals, is an open-pit mining operation extracting a large porphyry copper deposit southwest of Salt Lake City, Utah, in the Oquirrh Mountains. The mine is the largest man-made excavation, and deepest open-pit mine in the world, which is considered to have produced more copper than any other mine in history – more than 19,000,000 short tons. The mine is owned by Rio Tinto Group, a British-Australian multinational corporation. The copper operations at Bingham Canyon Mine are managed through Kennecott Utah Copper Corporation which operates the mine, a concentrator plant, a smelter, and a refinery. The mine has been in production since 1906, and has resulted in the creation of a pit over 0.75 miles (1,210 m) deep, 2.5 miles (4 km) wide, and covering 1,900 acres. It was designated a National Historic Landmark in 1966 under the name Bingham Canyon Open Pit Copper Mine.

The Ferris-Haggerty Mine Site was one of the richest components of the Grand Encampment Mining District in Carbon County, Wyoming. The site was first exploited by Ed Haggerty, a prospector from Whitehaven, England, in 1897 when he established the Rudefeha Mine that would later be known as the Ferris-Haggerty Mine on a rich deposit of copper ore. Haggerty was backed by George Ferris and other investors, of whom all but Ferris dropped out. The partners sold an interest to Willis George Emerson, who raised investment funding for improvements to the mine. These facilities included an engineering feat of its day by developing a 16-mile (26 km) aerial tramway to carry high grade copper mined at the Ferris-Haggerty Mine (FHM) over the Continental Divide to the smelter in Encampment. The tramway was longest aerial tramway the world had ever seen. The mine was eventually acquired by the North American Copper Company for 1.23 billion. By 1904 the mine had produced $1.4 million in copper ore, and was sold to the Penn-Wyoming Copper Company. However, even with copper prices peaking in 1907, the company had difficulty making a profit from the remote mine site. The company was over-capitalized and under-insured and was suffered devastating fires at the mine site in March 1906 and May 1907 which halted production. Business disputes and a fall in copper prices prevented re-opening of the mine even after it was rebuilt. Machinery was salvaged after a foreclosure in 1913. A total of 23 million pounds of copper ore was extracted from the mine during its life.
Devon Great Consols was a copper mine near Tavistock in Devon. The lease on the site was taken from the Duke of Bedford in 1844 by a group of investors. The 1,024 shares, sold at one pound each, were divided among the six men. Earlier attempts to mine this property had all ended in failure.

The Britannia Mines Concentrator is a National Historic Site of Canada.

The International Smelting and Refining Company was a subsidiary of Anaconda Copper that operated primarily out of the International Smelter near Tooele, Utah. The International Smelter began operation in 1910 as a copper producer handling ores from Bingham Canyon and was expanded into a lead smelting operation in 1912. Copper smelting finished at International in 1946, and the lead smelter shut down in January 1972. The closure of the smelter would lead to the associated Tooele Valley Railway to be shut down ten years later in 1982. The company also handled several other Anaconda owned interests. After the shut down of several of the International Smelting sites, environmental reclamation has been performed by Anaconda Copper's successor company ARCO and the EPA Superfund program.
