Investigation of extractive separation of uranium and vanadium from sulphuric acid leaching liquors of uranium ore (1)

Creators

Description

Condition of extractive separation of U and V from sulphuric acid leaching liquors of uranium ore by HDEHP was confirmed. For high selectivity of uranium extraction concentration of solvent, phase contact time and pH of aqueous solution must be decreased. To increase extractive capacity of vanadium, above indices have to be increased reversibly. Capacity of HDEHP for U is 80-100g/mol, for V 17-21g/mol. (Author)
