Abstract
A silver recovery system including a container having an inlet and an outlet, a core member positioned within the container, a filler material adjacent to the core member and being of a metal above silver in the electromotive force series, and a non-metallic mesh material positioned within 3/32 of an inch from an exterior surface of the filler material. The mesh material has a mesh size suitable for allowing water to pass therethrough. A securing member extends around the exterior surface of the mesh material so as to maintain the mesh material in surface-to-surface contact with the filler material. The mesh material generally surrounds the exterior surface of the filler material. The core member has a central tubular member with a plurality of openings formed radially through a wall thereof. A non-reactive material is affixed within the central tubular member so as to allow silver to plate thereon.
