In situ recovery, an alternative to conventional methods

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 (O'Gorman et al., 2004). ISR trials were carried out at several sites near Mount Isa, Queens-land in the1970s(O'Gormanet al., 2004). The

4 Uranium Mining, Processing, and Reclamation

In situ leaching (ISL), also known as solution mining, or in situ recovery (ISR) in North America, involves leaving the uranium ore in the ground, and recovering the uranium by dissolving it from the uranium-bearing minerals by injecting carbonated solution or mild acid and pumping the leached uranium in a pregnant solution to the surface where

Use of a Tracer for In Situ Stope Leaching Solution

After blasting, leach solutions containing chemical solvents and/or bacteria are circulated through the fragmented ore to dissolve the desired mineral (figure 1). The resulting mineral-rich solution (pregnant leach solution) is pumped to a processing facility where the product is removed, and the leach solution is regenerated for reuse

(PDF) Mining of valuable metals: in situ and heap leaching

In situ leaching (ISL), sometimes referred to as solution mining or in situ recovery (ISR), is a process of dissolving minerals such as copper or uranium directly in the ore deposit. Using a series of boreholes, a flow of leach solution is established allowing to wash the ore and to recover the fluid for processing.

Nedyalkov (1996) reported the first ISR activity at the Sclishte in 1961. From 1981, ISL of broken hard rock was also used to increase the yield from mined-out conventional underground mines.

Uranium element extraction method – in

Most of the uranium mining that is done today is done in-situ leaching technique. This method does not involve digging at the surface nor underground. The minerals that we get from this technique is mostly soluble, e.g, potash, potassium chloride, sodium chloride, sodium sulfate and uranium oxide which can be dissolved in water.
