Welcome to Precious Metals Processing Consultants, Inc. (PMPC)

PMPC specializes in the electrolytic recovery of heavy and precious metals from many different types of solutions with a wide range of pH. For 30 years we have been developing technology and offering innovative and creative solutions to electrolytic metal recovery problems. We have several off-the-shelf systems but are equally interested in designing systems to meet your needs.

Gold Bug®

Years ago, Precious Metals Processing Consultants, Inc. developed and patented a revolutionary type of electrolytic recovery system, the Gold Bug®. Gold recovery and platinum recovery does not have to be expensive or difficult.

GoldBug Gold and Platinum electrolytic recovery unit

The Gold Bug® is used very successfully with all of the precious metals including silver, palladium, palladium-nickel, platinum, rhodium and iridium. Various types of solutions of copper, cadmium, tin, tin-lead have all been successfully treated to concentrations of less than 5 ppm with the Gold Bug®.

Our new product, the Dummycell™, can sit at the bottom of your nickel tank and continuously remove your copper while you plate with no nickel co-plate. The ideal electrolytic recovery system for cutting down on waste that will keep your bath to less then 2ppm.

Dummycell Nickel Recovery Unit

The Dummycell™ is a system comprising a small pump, a power supply and a collection canister which actually sits at the bottom of your nickel tank. It employs an expanded surface area cathode which translates into a very low current density.

The Ionnet™ system. A serious electrolytic recovery system without the bells and whistles. Just pure recovery power in an elegantly simple design, inexpensively priced. What distinguishes the Ionnet most from other electrowinning systems is the expanded surface area cathodes and

the unique solution flow design. It has been reported to us that 60% - 80% of the free cyanide in a 500 gallon solution was destroyed in 48 hours of operation at 400 amps. While it would take more time to destroy I00% of the cyanide than it takes to remove all of the metals from solution, any cyanide reduction is helpful for total cyanide destruction and ultimate disposal of the solution.

Imagine recovering 20 kg of nickel per day or 100 kg of silver or 40 kg of gold. This is no longer a pipe dream. 20 years field testing of the original Ionnet makes these claims for IonnetX, the latest version of the most efficient electro-winning system yet devised, a reality.

IonnetX nickel, gold, and silver recovery system

"Order of magnitude" design changes have made the IonnetX system, remarkably user-friendly and reliably maintenance-free. IonnetX’s performance in a "real world" plating shop has astounded the management of one of the world's largest nickel-chrome operations.
