FIELD: non-ferrous metallurgy. SUBSTANCE: preliminary neutralization of solution is carried out in zinc sorption extraction from sulfate solutions using its contact to strong basic anion in hydroxy form at 1:(200 - 500) relation of weights between anion and solution, which is carried out until pH equals 4.3 to 4.6. Then the solution is put in contact with carboxylic cation. EFFECT: highly efficient zinc extraction. 4 dwg
