FIELD: metallurgy.
SUBSTANCE: method of germanium extraction from sulfuric solutions includes germanium extraction by organic phase with chelating extractant, containing N,O- donor atoms, in diluter and germanium re-extraction by solution of caustic soda. Additionally extraction is implemented by organic phase in the form of mixture of chelating extractant, containing N,O-donor atoms, with bis-(2,4,4,-trimethyl amyl) dithiophosphonic acids (CYANEX 301) in diluter at molar ratio of chelating extractant and CYANEX 301 in organic phase =0.25÷4.5:1.
EFFECT: increasing of extraction ability of system at extraction of germanium from sulfuric solutions, reduction of chelating extractant content in organic phase, implementation of extraction in area of low acidity.
