Investigations on the removal of iron from phosphoric acid by precipitation method were carried out using pure and commercial sodium sulphides. The effect of iron on the extraction of uranium from phosphoric acid using a mixture of di-2-ethylhexyl phosphoric acid (HDEHP) and a commercial trioctyl phosphine oxide (CYANEX 921) in kerosene has been investigated. The influence of HDEHP, CYANEX 921, Fe (III), sulphide concentrations as well as temperature on the extraction of U (VI) from phosphoric acid were separately investigated. The results are compared and optimum conditions for monitoring the effect of iron and sulphide on the extraction of uranium from phosphoric acid are proposed.
