Copper Concentrate

Copper concentrate is the most basic form of copper product sold by Freeport-McMoRan (FCX). We are one of world's leading producers of copper concentrate.

The world class Grasberg complex, located in the province of Papua, Indonesia produces copper concentrate through FCX’s affiliate, PT Freeport Indonesia. Approximately 50% of PT Freeport Indonesia concentrates are sold to affiliated smelters, Atlantic Copper, located in Spain and PT Smelting, located in Indonesia. The balance of the concentrate produced is sold primarily under long-term sales agreements mostly to major smelting companies in Asia. The concentrates produced in Indonesia generally contain 27 to 30 percent copper and approximately one ounce of gold per ton and are utilized as a base feed for many smelters in the industry.   

Copper concentrate produced at the mines in North and South America generally contain 20 percent to 30 percent copper and is the resulting product after mine ore (containing less than 1 percent copper) has been crushed, milled and concentrated. FCX has a controlling interest in the Cerro Verde mine located southwest of Arequipa, Peru.

The Cerro Verde expansion project commenced operations in September 2015 and is currently operating at full rates. Cerro Verde's expanded operations will benefit from its large-scale, long-lived reserves and cost efficiencies. The project expanded the concentrator facilities from 120,000 metric tons of ore per day to 360,000 metric tons of ore per day and is expected to provide incremental annual production of approximately 600 million pounds of copper and 15 million pounds of molybdenum. Cerro Verde’s concentrate production is transported approximately 70 miles by truck and rail for shipment to international markets.

In North America, FCX produces copper concentrate at four of our mines, Morenci, Bagdad, Sierrita and Chino. The majority of this concentrate production is shipped to the company's smelter in Miami Arizona, where anodes are produced. These anodes are then sent to the electrolytic refinery in El Paso, Texas where they are used to produce copper cathode.
