approximately 15 to 25% of U. S. copper. The recovery of copper through passive in-situ methods such as those used at Bingham Canyon during the 1880s eventually led to a more active approach, where water from underground mine sumps was applied to the ores and the resulting copper-bearing solutions collected and the copper recovered.

Jun 25, 2019 Todays infographic from Excelsior Mining Corp. outlines a unique mining method, In-Situ Recovery ISR, also known as In-Situ Mining. An Intro to In-Situ Mining. ISR is not a recent innovation in the mining sector. In fact, ISR has been used for the past 50 years in uranium mining, and 48% of the worlds uranium gets mined this way.
Learn the facts about in-situ copper recovery. Learn the facts about Todays Green Mining. Location. Gunnison Copper spans 9,560 acres between the cities of Benson and Willcox. The project is located within the heart of Arizonas Copper Porphyry Belt.
Oct 14, 2021 The project is a low cost, environmentally friendly in-situ recovery copper extraction project that is permitted to 125 million pounds per year of copper cathode production.
The deposit also is naturally highly fractured and most of the copper is located on the surface of the open fracture veins, providing all of the necessary conditions for in-situ recovery. Extraction is conducted via a closed loop system of delivery and recovery wells. Each delivery well is surrounded by four recovery wells each recovery well is in turn surrounded by four delivery
In-situ copper recovery requires unique hydrogeological conditions that happen to be in Florence. Unlike orebodies that are made up of solid rock, this deposit is naturally porous and shattered, allowing the extraction solution to easily flow through it. This means the copper can be extracted without the use of pressure.
What is In-Situ Recovery (ISR)? ISR is an environmentally-friendly process by which copper can be extracted from the ground with minimal disturbance to the surface environment. ISR mining has a long history, starting with uranium mining in the 1960s. Arizona also has a positive track record for ISR permitting.
Florence Copper will soon be a large-scale, commercial mining facility operating in Florence, Arizona that will produce over one billion pounds of high-quality copper cathode using revolutionary technology called in-situ copper recovery (ISCR). The facility will set a new standard for conservation and environmental protection in copper mining.
What is. InSitu Recovery Mining? Metals (Copper, Gold etc) are recovered In Situ by firstly dissolving the commodity in place and then extracting them using a system of injection and extraction bores or wells. Most times ISR accelerates what is already happening naturally within the bedrock and water table.
Mar 20, 2012 The Gunnison Copper Project is located close to the required infrastructure and its oxide resource has the potential to be mined using in-situ recovery methods. The Excelsior team consists of experienced professionals with proven track records of advancing projects towards production.
In the 1970s and early 1980s an in situ leaching project was carried out to extract copper from oxide ores at Miami, Arizona. This in situ leaching project operated for 7 years and closed down in 1982 (OGorman et al., 2004). ISR trials were carried out at several sites near Mount Isa, Queens-land in the1970s(OGormanet al., 2004). The ...
