Copper mining in Arizona, a state of the United States, has been a major industry since the 19th century. In 2007 Arizona was the leading copper-producing state in the US, producing 750 thousand metric tons of copper, worth a record $5.54 billion. Arizona's copper production was 60% of the total for the United States.
Resolution Copper is a proposed mine that can supply the world with the copper it needs to support ongoing technological and environmental innovation.
2 Recovery of Copper by Solution Mining Methods Solution mining replicates the natural process of oxidation and reduction, described above. Dilute acidic solutions are introduced to the copper-bearing ores, causing dissolution of soluble copper minerals (Table 1) remaining in the leached cap and underlying enrichment blanket.

The Florence copper project is an in-situ copper recovery (ISCR) project located in central Arizona, US. Image courtesy of Florence Copper Inc. The ISCR process will use a mixture of 99.5% water and 0.5% acid to dissolve copper in the underground bedrock ore. Image courtesy of Florence Copper Inc.
The Safford Copper Mine is near Safford, Arizona. Historically the site has been associated with the Lone Star Mining District which is now part of the San Carlos Reservation. The Safford Copper Mine is a surface mining operation. Initial production took place in 2006. The ore mined is composed of chrysocolla, chalcopyrite and bornite. The ore
Within the United States, mining and production of copper are primarily located in the West, specifically Arizona, New Mexico, Utah, Nevada and Montana. According to the United States Geological Survey (USGS), production in these states and Michigan account for more than 99% of domestic copper
Copper mining is still a major business in the state even though many mines played out and declined into the dry dusty land. The mining landscape of Arizona ranged from the desert floor to high in the mountains ranges of the state. Gold, silver, zinc, and lead have also played a part in the mining
A schematic diagram of the conventional process for the production of copper and the SX/EW process can be seen here. Conventional Copper Extraction . Conventionally, copper is recovered by a pyrometallurgical process known as smelting. In this process copper ore is mined, crushed, ground, concentrated, smelted and refined. The mining, crushing
A burgeoning mining industry stimulated early growth in the Arizona Territory, and by 1864 nearly 25 percent of the male, non-native populace was prospectors. By the 1870’s a plethora of hardrock mines were yielding prodigious volumes of copper, lead, zinc, silver and gold ore. In 1912, the newly christened state of Arizona supported 445
