Phelps Dodge Corporation was an
American mining company founded in 1834 as an import-export firm by
Anson Greene Phelps and his two British sons-in-law
William Earle Dodge, Sr. and
Daniel James. The latter two ran Phelp, James & Co., the part of the organization based in
Liverpool,
England. The import-export firm at first exported United States cotton from the Deep South to England, and imported various metals to the US needed for industrialization. With the expansion of the western frontier in North America, the corporation acquired mines and mining companies, including the large
Copper Queen Mine in Arizona. It operated its own mines and acquired railroads to carry its products. By the late 19th century, it was known as a mining company.
