Abstract

An apparatus and process for recovering metals from aqueous solutions by passing an aqueous solution (14), which contains dissolved metals, into a space (16) between two elongated electrodes (20, 30) of a treatment chamber (10). A very high voltage electric field is created in the treatment chamber (10) and is accompanied by a very small trickle current charge (i) to enhance adsorption, polarization, ion exchange or to otherwise agglomerate the dissolved metal, which is then recovered by filtering, adsorbing, exchanging or otherwise separating the metal from the water.
