Comment Morenci is the largest copper producer in North America and remains a major contributor to Phelps' copper output, which is second only to that of Chile's Codelco. In 1986, Phelps Dodge Morenci, Inc. was established as a partnership between Phelps Dodge Mining Company (85%) and Sumitomo Metal Mining Arizona Inc. The latter belongs to Sumitomo Corp. (75%) and Sumitomo Metal Mining Co Ltd.
Comment Type:
Production
Comment During 2006, Morenci mined 247 Million tons of ore, milled 4.1 Million tons grading 0.56% Cu, placed 230.70 Million tons of ore onto leach pads, recovered 14,993 tons copper in concentrate and electrowon 355,574 tons of copper cathode. (www.mining-technology.com/projects/morenci/)
Comment Type:
Commodity
Comment The Morenci porphyry copper deposit contains three types of copper ore minerals - oxide, secondary sulfide, and primary sulfide. The main oxide copper minerals are chrysocolla and malachite . The main secondary copper sulfide minerals are chalcocite and pyrite, and the main primary copper sulfide is chalcopyrite. There are many other primary and secondary minerals, including molybdenite, galena and sphalerite and two types of turquoise - hard, flawless blue and spider webbed. (FCX 2009 10-K and other sources)
