==Mining==
The Miami mine is owned and operated by [[Freeport-McMoRan]]. Mining began in 1911 as the [[Inspiration mine]], and  the nation's first [[froth flotation]] copper concentrator to process sulfide minerals was built and began production in 1915. Inspiration was among the first to employ vat leaching in 1926 and precipitation plants to recover oxide minerals. Copper was mined underground until after World War II, when the first open-pit mining began. The plant's [[smelter]] was modernized in 1974 to meet Clean Air Act standards and further modernized and expanded in 1992. The success of a [[solvent extraction and electrowinning]]  plant commissioned in 1979 ended vat leaching by the mid-1980s,  and  the concentrator closed in 1986 as well. The copper rod mill was commissioned in 1966.<ref name=FMM>[http://www.freeportinarizona.com/our-company/az-operations/miami/ Miami mine] at Freeport-McMoRan. Accessed June 23, 2018.</ref>

Copper mining was suspended in September 2015.  Leaching/SX-EW operations will continue but are expected to decline over time.  The Miami smelter and rod plant continue to operate.  In 2016, copper production at Miami amounted to 25 million pounds of copper. In 2017, copper production was 19 million pounds,  and more than 740 people were employed there.<ref name=FMM/>

The [[Pinto Valley mine]] is also located near Miami.
