OverviewTechniquesHistoryDeposit typesExplorationUranium pricesPoliticsHealth risks

As with other types of hard rock mining there are several methods of extraction. In 2012, the percentage of the mined uranium produced by each mining method was: in-situ leach (44.9 percent), underground mining (26.2 percent), open pit (19.9 percent), and heap leaching (1.7 percent). The remaining 7.3% was derived as a byproduct of mining for other minerals, and miscellaneous recovery. In open pit mining, overburdenis removed by drilling and blasting to expose the ore body, which is then

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

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. The mining solution is injected into the aquifer

Impacts of Uranium In-Situ Leaching

From 1981, 23 ore deposits were mined by conventional underground mining techniques, 17 by in- situ leaching from the surface, and 11 by in-situ leaching in combination with conventional mining techniques. In 1990, 70% of the uranium produced was from in-situ leaching of ore deposits with very low grades of 0.02 - 0.07% of uranium [Kuzmanov1993]. In the years 1991 - 1992, 14,000 wells in 15
