Abstract
Depletion of uranium ore deposits is leading to a need for more efficient uranium extraction techniques. In this study, gas-phase electric discharge is applied to an aqueous leaching solution dispersed between electrodes as a technique for enhancing acidic extraction of uranium. Application of the electric discharge treatment resulted in a 1.5 to 2.0 times increase in the leaching rate and an improvement in uranium recovery of 4%. The enhanced extraction method was found to involve oxidation of ferrous ions in the acidic aqueous solution by nitrogen-containing ions generated in the spark discharge channels.
