Simple, economical method for reclaiming gold and other precious metals from processing rinse water and drag-out tanks. The ion exchange resin is considered to be hydrophilic in nature and displays excellent cation exchange resin properties and characteristics in absorbing positively charged metal ions from process streams. Up to three troy ounces of precious metal can be recovered per pound. Thus, even with our smallest unit containing just four pounds of resin, these systems can pay for themselves after their initial use. These precious metal recovery units are also effective in producing higher purity rinse water for improved rinse processing re-use. Various pump/chamber combinations provide for small laboratory operations up to 400 gallon large volume tanks.
