摘要 |
A method and a device for recovering metals from a metal-containing flow, wherein: a) the metal-containing flow (7) and a solvent (8) are supplied to a dissolving unit (1), whereby a metal-containing solution is formed; b) the metal-containing solution is then supplied to a concentration unit (2); c) the metal-containing solution is separated in the concentration unit into a small-volume flow (14) containing a high concentration of metal salts and/or metal hydroxides, and a large-volume flow (13) containing a low concentration of metal salts and/or metal hydroxides; d) the small-volume flow (14) containing a high concentration of metal salts and/or metal hydroxides is supplied to an electrochemical unit (5); 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 (16) containing one or more metals, and a flow (15) containing a low concentration of metal salts and/or metal hydroxides. |
