The conditions of obtaining of uranium concentrates by extraction of uranium from sulfate leach liquors using tri-n-octylamine are investigated. It has been shown that 0.1 M TnOA solution in kerosene contsining about 2 per cent (V/V) of n-octanol is suitable for the recovery of uranium from the Polish leach liquors.The use of kerosene as a diluent for TnOA needs the addition to the organic phase of some per cent of n-octyl alcohol. This addition causes an increase of the solubility of tri-n-octylamine salt in the organic phase, and a synergistic increase of the uranium extraction at the mole ratio of alcohol to amine ranging from 0.95 to 1.59, and a decrease of the iron extraction. An increase of uranium concentration in the organic phase causes a decrease of the extraction coefficients of the other cations present in leach liquors. An increase of pH value of the solution causes sn increase of the extraction of iron(III) snd uranium(IV) by TnOA. (auth)
