Description: Morenci is an open-pit copper mining complex.

  • Location: Southeast Arizona, about 50 miles northeast of Safford.
  • Ores: The Morenci mine is a porphyry copper deposit that has oxide and secondary sulfide mineralization, and primary sulfide mineralization. The predominant oxide copper mineral is chrysocolla. Chalcocite is the most important secondary copper sulfide mineral and chalcopyrite the dominant primary copper sulfide.
  • Processes and facilities: The Morenci operation includes a 50,000 mtd concentrator that produces copper and molybdenum concentrates; a 68,000 mtd crushed-ore leach pad and stacking system; a low-grade run-of-mine leaching system; four solution extract (SX) plants; and three electrowinning (EW) tank houses that produce copper cathode. Morenci also has a concentrate leach direct-electrowinning facility, which was commissioned in third-quarter 2007 and processed copper concentrate until early 2009 when it was placed on care-and- maintenance status.
