What is “In Situ” Mining? Black Hills Clean Water Alliance

Mar 16, 2017· In situ leach mining (ISL) is a method of uranium mining where hundreds of wells are drilled in a “grid pattern” over an ore body that is located in a groundwater aquifer. Water mixed with sodium bicarbonate concentrate is pumped down into the aquifer, across the uranium ore bed, and them up and out other wells.

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
