Abstract

A high performance electrochemical cell is useful for recovery of metal from aqueous solutions. The electrochemical cell has a cathode assembly that includes a nonporous support member, a primary cathode, and a nonconductive or conductive porous material covering the primary cathode. An anode is spaced apart from the cathode assembly. Fluid is caused to flow through the porous material to the primary cathode, through openings or fluid collection channels in the nonporous support member, and uniformly out of the cell. Uniform and efficient deposition of metal is accomplished over the entire primary cathode because of modulation of fluid flow and increased mass transfer.
