Morenci Copper Mine, Arizona
· Lowgrade ore is ballmilled before being agglomerated and dumpleached to recover its copper content. The Detroit Copper Company started mining at Morenci, 16km south of Silver City, Arizona, in 1872. Copper Queen Consolidated Mining bought the property in 1885, with the company name changed to Phelps Dodge in 1917.
