In Situ Recovery Technology

Naturally - uranium and its decay products, radium and radon, cause groundwater to become radioactive and to exceed federal and state drinking water limits - making the natural groundwater present with uranium ore suitable only for industrial purposes.

What is In-situ Recovery?

  • In-situ recovery (“ISR”) is an noninvasive mining process where uranium is extracted from sandstone aquifers by reversing the natural process which deposited the uranium.
  • Oxygen is added to the existing groundwater and this is used to leach the uranium from sands.
  • Uranium is removed from the water by passing the water over ion exchange resin, much like in a domestic water softener.
  • The loaded resin is then processed.
  • Finally, the groundwater is restored consistent with its previous quality and use.
