Metal conductive sponge for precious metal recovery from dragout solution

Can you help me with information on metal conductive sponge for precious metal removing from dragout solution?

Copper plated foam cathodes are sold as part of "Retec" electrolytic treatment units. I believe they are now owned by US Filter.

I've used degreased 00 steel wool ⇦ this on eBay or Amazon [affil links] in similar applications.

Hi Joel,
Most platers out there use a resin exchange column to recover gold from drag-out solutions. There are other ways to do it, but many are ineffective compared to resins. A reputable precious metal / equipment supplier can set you up with a unit. This website has such advertisers and contributors. Good Luck!
