Removal of Trace Elements by Cupric Oxide Nanoparticles

ISR uses water-based oxidizing solutions to leach uranium from the underground ore body, after which the uranium is extracted from the leachate through an ion exchange process 8. To maintain a negative water balance in the ore body, a portion of the leachate, called production bleed water (PBW), is bled off.
