What is "In Situ" Mining? – Protect Water for Future .

What is in situ leach mining? 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.
