FIELD: hydrometallurgy.
SUBSTANCE: invention relates to recovering metal ions from aqueous solutions with the aid of clay minerals and can find use in nonferrous and ferrous metallurgies as well as in waste water treatment. Essence of invention resides in adding clay materials to solution in question followed by stirring and settling. Recovery of cations is effected at pH 2.6 to 10 over a period of time not exceeding 120 min and recovery of anions at pH 1 to 4 during at most 30 min. Clay minerals utilized are sea-origin hydromicas Irilit-1 and Irilit-7.
EFFECT: enhanced of metal ions recovery efficiency, reduced expenses due to use of non-costly sorbents, and reduced consumption of reagents.
