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.
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.
In situ leaching (ISL) is an attractive technique that enables copper recovery from copper oxide ores that are either low-grade or located at depths too great to be economically exploited through conventional methods. At present, in situ leaching (ISL) has been applied to intact copper oxide ores, in particular, those which (i) present a good …

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****."
We would like to show you a description here but the site won't allow us.

Within the United States, mining and production of copper are primarily located in the West, specifically Arizona, New Mexico, Utah, Nevada and Montana. According to the United States Geological Survey (USGS), production in these states and Michigan account for more than 99% of domestic copper production.
The use of ammonia as a leaching agent in the recovery of copper from ores and concentrates has a number of potential benefits. These include the ability to treat ores with an acid consuming gangue, non-corrosivity, the insolubility of iron in the solution and increased selectivity. This paper reviews the previous and current use of ammonia …
