  • Process for extracting and recovering metals from aqueous solutions
    Patent number: 7476300
    Abstract: An apparatus and process for recovering metals from aqueous solutions by passing an aqueous solution, which contains dissolved metals, into a space between two elongated electrodes of a treatment chamber. A very high voltage electric field is created in the treatment chamber and is accompanied by a very small trickle current charge 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.
    Type: Grant
