FIELD: chemical technology. SUBSTANCE: separation of manganese of solutions and pulp which comprise uranium and products of its radioactive decay. Solutions which comprises manganese and radioactive elements having pH 4.5 are alkalized to pH 7.0, the process is carried out with the help of lime. Solution is separated of precipitate, then manganese products are precipitated with the help of carbonate salts of ammonium or of alkaline metals. EFFECT: decreased content of radioactive impurities in products of utilization of manganese.
