Tummalapalle uranium mine - Wikipedia

Over the past 60 years of uranium process development only a few commercial uranium plants have adopted a pressure leaching process in their flowsheet. The selection of acid versus alkaline pressure leaching is related to the uranium and gangue mineralogy. Tetravalent (U+4) uranium has to be oxidized to hexavalent (U+6) uranium to be soluble.

A new Zircex flowsheet is proposed in which the nonvolatile products from hydrochlorination of uranium-zirconium alloys are chlorinated with carbon tetrachloride, thereby avoiding the loss of 1 to 6% of the uranium observed in engineering development studies of the older flowsheet for STR fuel in which the hydrochlorination residue was dissolved in nitric acid.

Uranium Extraction History using Pressure Leaching

•The UREX+3 flowsheet consists of three primary separations processes •The first is a modification of the industrially used continuous solvent extraction process using tributyl phosphate −Largest-mass component, uranium, is removed −Plutonium and neptunium (possibly with some uranium) are collected together •The second process, Reverse
