heap leaching vs in situ copper

Understanding mineral transformations of composite copper sulphide ores and the associated reaction mechanism at low to medium temperatures in acidic solutions with oxidant restriction is important for in situ recovery operations because natural ore bodies typically comprise multiple sulphide species and their dissolution is oxidant consuming.

During the last decade, the feasibility of applying the in situ leaching technology to the recovery of copper from deeply buried deposits containing chalcopyrite has received much attention. The major incentive for using this technology is that under certain circumstances, copper in deep underground deposits, which cannot be mined economically by conventional means, can be recovered ...

The Moonta Copper & Gold ISR project | EnviroCopper

In-Situ Recovery (ISR) is now a mature technology for uranium recovery . Developed in USA and USSR in the s, it now accounts for nearly 50% of the world's production. Current project developments indicate that copper ISR is now coming of age. Copper in-place leaching has a long history. Since the 1950 60s it has been applied to low- -grade

In situ leaching (ISL), also known as in situ recovery, is a low capital cost method of extracting uranium, copper or potash from suitable deposits. A suitable deposit is one where the commodity is located in saturated permeable horizons or distinctive geological areas that are bounded above and below by impermeable strata.

Taseko's wholly owned Florence Copper, an in-situ copper recovery project, is located midway between Phoenix and Tucson near the community of Florence, Arizona. Development of the project is being performed in two phases – the first phase is a production test facility, which is followed by the second phase commercial facility.

NRC: In Situ Recovery Facilities

In situ leaching (ISL), solution mining, or in situ recovery (ISR) involves dissolving uranium in the ground and pumping the solution to the surface where the minerals can be recovered. Information from the World Nuclear Association, the global private-sector organization that provides information on nuclear power, nuclear energy, and the role of nuclear in sustainable development.

Copper is the most popular commodity (after uranium) that is mined by ISR (Table 1). There are references to primitive forms of in situ leaching of copper in Roman times, and maybe even long before that in China (O'Gorman et al., 2004). The San Manuel copper mine in Arizona is the best known copper mine exploited by ISR (O'Gorman et al., 2004).

Whilst to-date in situ recovery is commonly only used in Australia for mining uranium, and in large scale operations across the globe for mining potash, salt, uranium and copper, global interest is growing in its use for other minerals such as nickel, silver, zinc, and cobalt.
