Ion exchange studies on acid leach liquor from Durango residue
Acid leach liquor from the Durango, Colorado plant of the Vanadium Corporation of America has been treated with ion exchange resins for uranium recovery in columnwise operation. Several competitive resins were used to determine maximum recovery of uranium under varying conditions of pH, degree of reduction, dilution, and flow rate. The results obtained indicate that the liquor should be reduced to a potential of approximately minus 400 mv (Pt vs the saturated calomel electrode), the pH brought to approximately 1.5, and a retention time of five minutes or less maintained during adsorption to give ...
