Uranium mining - Wikipedia

In 2012, the percentage of the mined uranium produced by each mining method was: in-situ leach (449 percent), underground mining (262 percent), open pit (199 percent), and heap leaching (17 percent) The remaining 73% was derived as a byproduct of miningIn-situ copper leaching is a proven technology | MINING,In-situ copper leaching is a proven technology In Situ leaching has the benefit of being a low environmental impact mining operation with little infrastructure and capital investment required It can be used when the geologic environment is suitable (copper oxides and fragmented orebody) and has the potential to be a very profitable enterpriseImpacts 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
