Ion Exchange Resin Evaluation In Uranium Recovery

This led to the application of anion exchange resins to concentrate and purify the uranium product. While this is the simplest statement of what an ion exchange resin does in the recovery of uranium, it should not be forgotten that the industry is continuing to evolve new methods in mining and processing which affect ion exchange operation.

Uranium - Home | DuPont

Groundwater Remediation . Uranium is a natural element found in groundwater throughout the world and regulated in some countries. Uranium is usually present as the monovalent uranyl ionic complex (U 3 O 8-) at very low levels in groundwater and thus the most cost effective treatment is to remove the uranium with a highly selective ion exchange resin and then dispose of the uranium-loaded resin.
