ABSTRACT:
The invention concerns a method for the liquid/liquid extraction of uranium from phosphoric acid with the aid of alkylamine polyphosphate and/or alkylamine metaphosphate compounds, dissolved in organic solvents insoluble in water, in the presence of Fe.sup.II ions.
The uraniferous phosphoric acid is brought into contact with an organic phase. The organic phase is composed of a long-chain alkylamine polyphosphate and/or alkylamine metaphosphate compound and an organic solvent, the alkylamine in the alkyl residue containing 8 to 30, preferably 8 to 18 C-atoms corresponding to the formula ##STR1## R.sub.1 and R.sub.2 denoting hydrogen or alkyl radicals and R.sub.3 alkyl radicals, the polyphosphate and/or metaphosphate residue having 2 to 10,000 P-Atoms per molecule and being of the straight-chain and/or link-chain or cyclic type. The uranium is transferred from the aqueous into the organic phase from which the uranium is reextracted in the know way.
