Morenci Copper Mine, Arizona Mining Technology ,

“Morenci is the largest copper producer in North America and remains a major contributor to Phelps’s copper output.” When hydrometallurgical processing started, these two mills worked in parallel with two leaching / solvent extraction operations and one electrowinning tankhouse.

Phelps Dodge Morenci Has Converted All Copper

In 1921, Phelps Dodge purchased the assets of the Arizona Copper Company and both the Detroit Mining Company and Arizona Copper Company, along with their names, were consolidated under the Phelps Dodge banner. From that time until the mid-1980s, processing of ore from the Morenci and Metcalf mines was confined to the concentration and smelting of sulfide ores. The Morenci and Metcalf pits were

Producing Copper Nature"s Way: Bioleaching

In 2001, bioleaching constituted approximately 10% of Chilean copper production and heap and dump leaching, in general, constituted approximately 30% of Chilean production. 2 The first Chilean plant to be put into operation was S.M. Pudahuel.

Expansion Program Propels Morenci’s Copper Production

When copper prices bottomed out in the late 1990s, Morenci looked at its reserves, the economics and decided to idle milling operations in favor of heap-leaching techniques. “In the early 2000s, we started crushing and stacking leachable ore on the pads, which sustained the mining operations,” said Josh Olmsted, senior vice president, Morenci operations. “During this period, most of the

As a result, Morenci"s copper production is expected to average over 480 kt over the next five years which would make it the second largest copper producer in the world. Molybdenum production will

THE APPLICATION OF BIOLEACHING TO BASE METAL SULFIDES

soluble copper oxide heap leach operations were adapted to treat secondary copper sulfide ores. The technology evolved in Chile and Australia, with the realisation that oxygen (and not acid) is the primary reagent in the process. This resulted in the design of aerated heaps and better operational control systems, which vastly improved the rate and extent of metal extraction achieved in the

Major Mines & Projects , Morenci Mine

The Morenci mine is a porphyry copper deposit that has oxide, secondary sulfide and primary sulfide mineralization. The predominant oxide copper mineral is chrysocolla. Chalcocite is the most important secondary copper sulfide mineral, with chalcopyrite as the dominant primary copper sulfide.

Copper Industry Feature–Copper Processing Remains

Subsequently, all heap leaching operations focused on the recovery of copper from copper oxides or secondary copper sulphides. Further investigations into the leaching of chalcopyrite identified that leaching temperatures in excess of 70°C and fine grinding of the ore to less than 0.05mm in size are key requirements to extract copper from chalcopyrite at an appreciable rate.
