Nacozari began with the discovery of mines in 1660. The first settlement was called Nuestra Señora del Rosario de Nacozari.
The mines were acquired by Anglo American U.B. Teader mining company in 1867, which sold them to Moctezuma Copper Co, a subsidiary of Phelps Dodge. American style housing was built, together with a library and a small hospital. Copper was hauled partially by mule trains, until the railroad was finished in 1904. By 1907, Nacozari had become the metropolis of far northeastern Sonora. It had 5,000 people, mostly Mexicans and Americans, with some Chinese. Phelps retained the mines until 1948 when they were exhausted.
A large mine, La Caridad, was discovered about 20 miles southeast of Nacozari in 1968. By 1979, the population of Nacozari was back to about 3,000. As Mexicana de Cobre, the federal government spent hundreds of millions of dollars to develop La Caridad, and revive other mines in the area. Nacozari was estimated to have 18,600 people in 1986, and 30,000 in 1989. La Caridad is ranked the third largest copper mine in the world.
The municipal seat was first called Placeritos de Nacozari but changed its name to Nacozari de García to honor the railroad engineer Jesús García, who saved the town from a dynamite explosion on 7 November 1907. Besides Nacozari, there are monuments to Jesús García in many other Mexican cities and towns. November 7 is the Day of the Railroader in Mexico. All except essential employees of the National Railways of Mexico get the day off. Many streets in Mexico are named Jesús García or the Héroe de Nacozari. Poems and songs have been written about him, and the accident. 
The main economic activitiy is the copper mine of Mina Mexicana de Cobre, S.A de C.V, which employs most of the labor force (3,012 workers in 2000). 
Cattle raising is also important with 16,375 head counted in the 2000 census. Calves are exported to the United States of America.
