Uranium can be recovered from industrial phosphoric acid by organophosphorous compounds, such as D2EHPA-TOPO. However, this mixture extracts, at the same time, a large number of ions with several positive charges (heavy metals). Investigations on the nature of the diluent give, generally, preference to kerosene, but little has been published about its hydrocarbon composition and its influence on the extractant system. This work illustrates the recovery of uranium from industrial phosphoric acid, as well as the distribution of Fe and Al, at each extraction stage, using both raw and sulfonated kerosene. From the results obtained, it was observed that treatment of kerosene improves the recovery of uranium up to 30% and reduces the co-extraction of Fe and Al by about 25% and 15%, respectively. Rare earths and thorium have also been analysed before and after extraction of uranium.
