Abstract
Value metal, for example, silver in a spent silver bearing photographic solution is efficiently recovered in an exchange mass comprising a particulate inert substrate, for example, cellulosic fibers, synthetic fibers or sponge particles, co-mingled and interlocking with elongate particles of replacement metal, for example, strands of steel wool; the substrate defines a non-channeling random flow paths for liquid flow, and inhibits carriage of recovered value metal by the flowing liquid.
