Description

Our rod and refining plant in El Paso, Texas, is a key contributor to our ranking as one of the world’s largest manufacturers of continuous cast copper rod, a main material used in the manufacturing of wire and cable products. The El Paso refinery has the potential to operate at an annual production capacity of about 900 million pounds of copper cathode, which is sufficient to refine all of the copper anode we produce at our Miami, Arizona operation. Our El Paso refinery also produces nickel carbonate, copper telluride and autoclaved slimes material containing gold, silver, platinum and palladium.

Did you know?

The majority of the copper produced at our U.S. copper mines and refined in our El Paso, Texas refinery is consumed at our rod plants to produce copper rod, which is then sold to wire and cable manufacturers. The remainder of our U.S. copper production is sold in the form of copper cathode or copper concentrate under U.S. dollar-denominated annual contracts. Generally, copper cathode is sold to rod, brass or tube fabricators. Cathode and rod contract prices are generally based on the COMEX monthly average settlement prices for the month of shipment and include a premium.

Ores

The Morenci mine is a porphyry copper deposit that has oxide, 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 consists of two concentrators capable of milling 132,000 metric tons of ore per day (mtd), which produce copper and molybdenum concentrate; a 72,500 mtd, crushed-ore leach pad and stacking system; a low-grade run-of-mine (ROM) leaching system; four SX plants; and three EW tank houses that produce copper cathode. Total EW tank house capacity is approximately 900 million pounds of copper per year. Morenci’s available mining fleet consists of one hundred and forty-one 235-metric ton haul trucks and three 372 metric-ton haul trucks loaded by 13 shovels with bucket sizes ranging from 47 to 59 cubic meters, which are capable of moving an average of 803,000 metric tons of material per day.

Background

Phelps Dodge & Company invested $50,000 in the property in 1881, marking the New York mercantile’s first venture into mining. Through acquisition, Phelps Dodge & Company consolidated all mining operations in the district by 1921.

Processes and facilities

The Sierrita operation includes a 100,000 metric ton-per-day concentrator that produces copper and molybdenum concentrate. Sierrita also produces copper from a ROM oxide-leaching system. Cathode copper is plated at the Twin Buttes EW facility, which has a design capacity of approximately 50 million pounds of copper per year. The Sierrita operation also has molybdenum facilities consisting of a leaching circuit, two molybdenum roasters and a packaging facility. The molybdenum facilities process molybdenum concentrate produced by Sierrita, from our other mines and from third-party sources.

Description

Miami includes an open-pit copper mine, a smelter and a rod mill.

Location

90 miles east of Phoenix, in the heart of Arizona’s historic Globe-Miami mining district.

Did you know?

The Miami mine historically had been the major copper producer in the Globe-Miami mining area, one of America’s premier copper mining districts.

Ores

The Miami mine is a porphyry copper deposit that has leachable oxide and secondary sulfide mineralization. The predominant oxide copper minerals are chrysocolla, copper-bearing clays, malachite and azurite. Chalcocite and covellite are the most important secondary copper sulfide minerals.

Processes and facilities

Since about 1915, the Miami mining operation had processed copper ore using both flotation and leaching technologies. The design capacity of the SX/EW plant is 200 million pounds of copper per year. Miami is no longer mining ore, but currently produces copper through leaching material already placed on stockpiles.

Background

The first prospecting expeditions visited the area in the 1860s. Copper was mined underground until after World War II, when the first open-pit mining began. Miami was among the first to employ “vat leaching” (1926) and precipitation plants to recover oxide minerals. It did this in conjunction with its flotation concentrator, which processed sulfide minerals. The plant’s smelter was modernized in 1974 to meet Clean Air Act standards and further modernized and expanded in 1992. The success of an SX/EW plant commissioned in 1979 led to the demise of vat leaching by the mid-1980s and ultimately the concentrator in 1986. The rod mill was commissioned in 1966 and the refinery in 1993 (the refinery was permanently closed in 2005).
