Phelps Dodge Morenci Has Converted All Copper Production to Mine-for-Leach

Early mine-for-leach was confined to high-grade concentrates of oxidized copper; namely, malachite, azurite and tenorite. Today's mine-for-leach will include both oxide and sulfide ore minerals. The conversion to mine-for-leach maintains the property's annual production rate of approximately 800 million pounds (360,000 mt) of copper per year.

Processes Of Copper Mining Crusher

It is a subsidiary of Atlas Consolidated Mining and has a long history of copper mining dating back to the 1970s-1980s when it was the 3rd largest copper mine in the world. Carmen Copper uses conventional open pit mining and milling processes to extract copper concentrate from ore, including crushing, grinding, flotation, and dewatering.

Why Copper Leaching Is the Future of Copper Mining

Almost 50% of all mining waste comes from copper**, and there are a whopping 4.3 gigatons of tailings produced every year***. Copper leaching can squeeze copper out of decades of tailings, and at minimal expense. As one industry head put it: "It's the equivalent of bringing on a new mine without having all the capital cost****."
