The invention relates to ecology, particularly, to metal extraction from aqueous solutions, including waste water with high metal ion concentration.It offers a metal extraction method from aqueous solution by powder addition of another metal, which has lower standard potential than extracted metal. The proposed solution differs from known, by the suspension processed using hydraulic micro impacts. As hydraulic micro impacts source is used a high speed disperser-cavitation device, impulse electric discharges, or by using pulse electromagnetic field.
