Impacts of Uranium In-Situ Leaching

In the case of in-situ leaching (ISL) - also called in-situ recovery (ISR), or solution mining - the uranium-bearing ore is not removed from its geological deposit, but a leaching liquid is injected through wells into the ore deposit, and the uranium-bearing liquid is pumped to the surface from other wells. In-situ leaching gains importance for the exploitation of low grade ore deposits, for ...

Canadian Nuclear Association

Uranium mining methods. Uranium ore is extracted from the ground in one of three ways: open pit mining, underground mining or in-situ recovery. Open-pit mining When uranium ore is found near the surface, generally less than 100 metres deep, it is typically extracted by the open-pit mining method.

Uranium Mining

Other mining methods, such as in-situ leaching, where powerful chemicals are injected into the ground to leach uranium out of the ore, are some-times presented as a way of mining uranium without the need for milling operations. However, the prac-tice is associated with groundwater contamination that is impossible to remediate.

Methods of Metal Recovery by Microorganisms (2 Methods)

Pseudomonas aeruginosa can be employed in mining low grade uranium (0.02%) ore. This organism has been shown to accumulate about 100 mg uranium per one liter solution in less than ten seconds. Another organism, Rhizopus arrhizus is also effective for extracting uranium from waste water. Certain fungi have also found use in bioleaching.

THE NUCLEAR FUEL CYCLE

tin. The largest producers of uranium are currently Australia, Canada and Kazakhstan. The concentration of uranium in the ore can range from 0.03 to 20%.
