In Arizona, copper mining has been a major industry since the 19th century. In 2007, Arizona was the leading copper-producing state in the country, producing 750 thousand metric tons of copper, valued at $5.54 billion. Arizona's copper production was 60% of the total for the United States. Copper mining also produces gold and silver as byproducts. Byproduct molybdenum from copper mining makes Arizona the nation's second-largest producer of that metal. Although copper mineralization was found by the earliest Spanish explorers of Arizona, the territory was remote, and copper could seldom be profitably mined and shipped. Early Spanish, Mexican, and American prospectors searched for gold and silver, and ignored copper. It was not until the completion of the Southern Pacific Railroad in 1876 that copper became broadly economic to mine and ship to market.

The Copper Queen Mine was a copper mine in Cochise County, Arizona, United States. Its development led to the growth of the surrounding town of Bisbee in the 1880s. Its orebody ran 23% copper, an extraordinarily high grade. It was acquired by Phelps Dodge in 1885.
The New Cornelia mine is a currently inactive open-pit copper mine in Pima County, Arizona, United States. It was the only productive mine in the Ajo mining district, and is located just outside the town of Ajo, which was built as a company town to serve the New Cornelia mines. The roughly circular pit is one and a half miles across at its widest point, and 1,100 feet deep at the center. Although not generally regarded as a 'dam', the New Cornelia Mine Tailings is often cited as the largest dam structure in the United States with a volume of 7.4 billion cubic feet.

Silver City is a ghost town located at the mouth of Dragon Canyon on the west flank of the East Tintic Mountains in northeast Juab County in central Utah, United States. It was a silver mining town approximately 90 miles (140 km) south-southwest of Salt Lake City. This area was considered part of the Tintic Mining District and also produced bismuth, copper, gold, and lead. Settlement began with the first mining strikes here in 1869. Silver City was inhabited until 1930, after the mines played out. Jesse Knight, known as the "Mormon Wizard" for his ability to find ore easily, decided to build a smelter in Silver City because it had the flattest ground in all of the Tintic Mining District. Silver City had several mines in 1890, but the mines hit water and were abandoned. Now there is little left other than a few holes where mines were, and a number of tailings piles. The Silver City Cemetery, however, survives and is listed on the National Register of Historic Places.
