COMPOSITION AND METHOD FOR SOLUTION MINING OF URANIUM ORES

摘要

In the solution mining of uranium ores using an aqueous ammonium carbonate leaching solution containing hydrogen peroxide and/or molecular oxygen as oxidant, permeability of the ore formation during the leaching operation is improved by inclusion of a small amount of alkali metal silicate dissolved in the leaching solution. The silicate also improves the stability of the oxident in many instances.
