Hydrothermal Leaching of Nickel, Uranium and the Remaining Vanadium from Alkali Treated Boiler Ash Residue using Citric Acid

Abstract
I N this study; the boiler ash was subjected to a digestion process using citric acid solution.Previously the ash was treated with NaCO 3 -NaHCO 3 solution for vanadium leaching.In this step about 85% of the vanadium content was leached while nickel was not dissolved using the carbonate solution.The ash after vanadium dissolution was digested using citric acid for nickel and the remaining vanadium...
