RECOVERY OF URANIUM FROM ORES BY DIRECT LEACHING WITH ORGANIC SOLVENTS

Technical Report ·
OSTI ID:4307751
The process described is the only one which involves lower acid comsumption than an aqueous leach. The extractment used is a commercially available mixture of mono- and dioctyl esters of phosphoric acid diluted with a volatile solvent such as methylethyl ketone or hexone. It is essential that some mineral acid be addedd either to the solvent before contact with the ore or to the slurry of organic extractant and ore. For this use sulfuric acid was found to be superior to other mineral acids. The extracted urauium is stripped from the solvent by contact with hydrochloric acid as in the liquid-liquid extraction process. This process is not applicable to all types of ores. It works well with secondary (oxidized) ores but removes only pant of the uranium from primary ores. (J.E.D.)
