PRODUCTION OF AQUEOUS URANIUM SULPHATE SOLUTIONS

Patent

A process for dissolving U oxides in H/sub 2/SO/sub 4/ is given in which a metal fluoride is used to accelerate the reaction. The process can also be applied to slag or roasted dross from a fluoride process. In an example, a slag (30.5% U, 55% CaF/sub 2/, and MgF/sub 2/) was heated with 20% H/sub 2/SO/sub 4/ at 85 to 95 deg C for 1 hr. The U was completely dissolved. In another example, a U/sub 3/O/sub 8/ product which did not yield to a 12% H/sub 2/SO/sub treatment for 1 3/4 hours at 85 to 95 deg Cmore »« less
PRODUCTION OF AQUEOUS URANYL SULPHATE SOLUTION FROM URANIUM DROSS

Patent

A process for recovering U from scrap and U-production dross is offered. The U-containing material is burnt to oxide in air, mixed with lime, roasted at 600 to 1000 deg C, and mixed with H/sub 2/SO/sub 4/. After pH adjustment and filtering, the UO/sub 2/SO/sub 4/ solution can be converted to peroxide. (T.R.H.)
THE PRODUCTION OF URANIUM AND URANYL SULPHATE

Patent

A method is given for recovering U from bonab reduction slags. The crushed slag is roasted and moistened with concentrated H/sub 2/SO/sub 4/and heated. In an example 100 parts of slag containing 44% F, 29% Mg, 21% U, 4% C, and 2% O are crushed and roasted at 700 to 800 deg C for 4 hours, cooled, and ground to 200 mesh. Then it is mixed with 300 parts of 98% H/sub 2/SO/sub 4/ and heated at 250 deg C until no more HF is evolved. The resulting sludge is F free and contains all the U in acid-soluble form.more »« less

URANIUM RECOVERY AND PURIFICATION PROCESS AND PRODUCTION OF HIGH PURITY URANIUM TETRAFLUORIDE

Patent Bailes, R.H.; Long, R.S.; Grinstead, R.R.

A process is described wherein an anionic exchange technique is employed to separate uramium from a large variety of impurities. Very efficient and economical purification of contamimated uranium can be achieved by treatment of the contaminated uranium to produce a solution containing a high concentration of chloride. Under these conditions the uranium exists as an aniomic chloride complex. Then the uranium chloride complex is adsorbed from the solution on an aniomic exchange resin, whereby a portion of the impurities remain in the solution and others are retained with the uramium by the resin. The adsorbed impurities are then removed bymore »« less
