In North America, FCX operates seven open-pit copper mines — Morenci, Bagdad, Safford, Sierrita and Miami in Arizona, and Chino and Tyrone in New Mexico; and two molybdenum mines — Henderson and Climax in Colorado. Molybdenum concentrate, gold and silver are also produced by certain of FCX's North America copper mines.

El Teniente copper mine, the world's sixth biggest, is located 80km south of Santiago in the Andes mountain range in Chile. It is also the largest underground copper mine in the world. El Teniente was estimated to contain 15.2Mt of fine copper (1,538Mt of ore grading 0.99% copper) at the beginning of 2013.

Grinding and concentration together consume about 45 percent of the energy used in the pro-duction of cathode copper. Assuming an ore grade of 0.55 percent and a recovery rate of87.5 6.4 percent copper in the concentrate, concentrat-ing 1 ton of copper ore requires over 200 billion Btu, or approximately 42 million Btu/ton of cath-

Copper ore beneficiation methods. Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm.

If we consider only the top 20 copper mines with the most important reserves of copper (over 1,000 million tonnes of copper reserves) the average copper ore grade of this group is only 0.76% copper, including deposits with a high average copper ore grade, such as Tenke Fungurume with 2.32%Cu, Resolution with 1.5%Cu, Taimyr Peninsula (Nor'ilsk …

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

The Mill uses conventional crushing, grinding, and floatation methods to produce separate nickel and copper concentrates. Approximately 2,000 metric tonnes of ore will be milled per day. By utilizing the Humboldt Mill, we are able to extract more nickel and copper at lower grades.

Porphyry copper ores, usually medium to medium hard, require grinding to about 65-mesh to economically liberate the copper minerals from the gangue. Although a clean rougher tailing can often be achieved at 65-mesh the copper mineral is not liberated sufficiently to make a high grade copper concentrate, thus some form of regrinding is necessary ...
