THORIUM RECOVERY FROM BARREN URANIUM LEACH LIQUORS

Patent ·
OSTI ID:4685920
A low-cost process is patented for recovery of Th from acidic barren leach liquor containing Th, ferric iron, and phosphate in aqueous solution. The leach liquor is brought into intimate contact with a bed of metallic Fe, substantially in the absence of air. The soluble phosphate is transformed into a thorium-phosphate-containing sludge, which is precipitated from the solution and may be recovered from the barren leach liquor. Details of the process and examples are given. (M.P.G.)
