FIELD: metallurgy.
SUBSTANCE: uranium sorptive extraction method from sulfuric acid solutions and pulps is that the uranium sorption is carried out on the anionite exchanger of commixed basicity. Then the saturated anion exchanger is treated with 1.5-3.0% solution of H2SO4 at the anion exchanger ratio: solution of 1:1.5-2.0 and uranium is desorbed with 75-100 g/l of Na2CO3 at duration of 4-6 hours and the anion exchanger ratio of 1:2-3.
EFFECT: reduction of energy and material costs, simplification of the process and increase of its efficiency.
