FIELD: chemical industry, more particularly recovery of metals present in solutions both in anionic and cationic form. SUBSTANCE: initial flow of solution is made to form laminar stream and said stream is located between two laminar streams of pure water. Three-stream flow is subjected to the effect of electrostatic field with the result that ions leave solution and move in steam of water, anions moving towards anode, and cations, towards cathode. Stream of solution is then removed from flow, and ions are recovered on sorbent, metals present in the solution both in anionic and cationic form, solutions containing suspended finely dispersed mineral particles are subjected to processing. EFFECT: more efficient recovery method. 2 cl
