Uranium mining. 'Dalur' and 'Khiagda' produce uranium by in situ recovery (ISR) method. Unlike the traditional extraction method (extracting ore from the subsoil, its shattering and processing) with ISR uranium ore remains in place. Leaching reagent is pumped through the ore via well system, followed by extracting of the uraniumcontaining...

The Inkai operation is an in situ recovery uranium mine in south Kazakhstan that is owned and operated by JV Inkai which, in turn, is currently owned by Cameco (60%) and Kazatomprom (40%). Cameco's current interest in production from JV Inkai is % based on previous agreements with Kazatomprom.

Wyoming uranium mines only use insitu mining, a specific extraction process that involves chemicals. A proposal advanced by the EPA in 2017 to monitor this practice was abandoned last year.

Insitu leaching produces little waste rock and leaves a minimal environmental footprint. However, miners must monitor contamination of aquifers and ensure disposal of waste water. Insitu leaching accounts for about 48% of all uranium mining, while openpit and underground mining comprise about 47% of mining. The remaining 5% of mining occurs as a byproduct of other mining.
