Uranium is commonly found in water because it oxidized and its oxidized form is very water soluble. Conversely, when the soluble uranium comes into contact with a reducing environment (e.g., sulfides such as pyrite or hydrogen sulfide, and organic material such as coal, oil or gas), it falls from solution.Uranium enters an aquifer when it become

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
