ABSTRACT:
A unit for the recovery and removal of metal from solution employing a series of concentric cylindrical wire mesh electrodes. Alternating concentric electrode elements are connected to one another to provide interleaved anode and cathode elements. The cathode is a relatively fine wire mesh that is sandblasted to provide maximum cathode surface area. The electrode arrangement is held and positioned within a cylindrical container by a base plate having a series of annular concentric grooves into which the bottom edges of the electrode elements are received. The base plate stands up off the floor of the container to provide a shallow chamber between the base plate and a central inlet opening to the container. A plurality of holes in the base plate admit fluid from the chamber into the annular channels between the electrode elements. The configuration facilitates streaming of the solution along the channels and thus along the cathode surfaces. Solution travels up the annular channels between electrode elements and out and over an upper open rim of the container.
