Recovering uranium from wet process phosphoric acid with alkylphenyl phosphates
An improvement is described in the process for the recovery of uranium from a phosphoric acid solution. It is derived from the acidification of uraniferous phosphate ores including the steps of reducing the uranium in the phosphoric acid solution to the uranous form and contacting the resulting solution with a liquid-liquid solvent extraction agent which is a mixture of mono- and di-(Alkylphenyl) esters of orthophosphoric acid dissolved in an inert organic diluent, to effect recovery of the uranium with the liquid-liquid solvent extraction agent, the improvement being maintaining the proper ratio of the mono and di-components of the liquid-liquid solvent extraction mixture which comprises removing dissolved and entrained uranium process organics from the raffinate resulting from said liquid-liquid solvent extraction step and recycling the removed organics to said liquid-liquid solvent extraction step.
