<p>A method and a device for recovering metals from a metal-containing flow, wherein: a) the metal-containing flow and a solvent are supplied to a dissolving unit, whereby a metal-containing solution is formed; b) the metal-containing solution is then supplied to a concentration unit; c) the metal-containing solution is separated in the concentration unit into a small-volume flow containing a high concentration of metal salts and/or metal hydroxides, and a large-volume flo w containing a low concentration of metal salts and/or metal hydroxides; d) the small-volume flow containing a high concentration of meta l salts and/or metal hydroxides is supplied to an electrochemical unit; and e) the small-volume flow containing a high concentration of metal salts and/or metal hydroxides is separated in said electrochemical unit into a flow containing one or more metals, and a flow containing a low concentration of metal salts and/or metal hydroxides.</p> |
