Precious Metal Recovery & Refining Equipment · 99.8% purity
Precious Metal Electrolytic Recovery Machine
High-frequency pulse recovery that pulls gold and silver straight out of spent solution as metal.
Overview
What This Machine Is
Developed in-house, this machine reduces silver, gold, copper or nickel ions directly to metal under automatic intelligent control, reaching 99.8 percent purity with a recovery rate of 99 percent or better on gold and silver. Available in one, two, three and four-head configurations.
The problem it is built for
Drag-out tanks, strip solutions and rinse waters carry away real money, and the concentration is too low for anyone to bother with chemically. Electrolytic adsorption makes low-concentration recovery worth doing, and the residual liquid comes back inside discharge limits.

Features
What Is Built Into It
Electrolytic adsorption, automatically controlled
Metal ions in solution are reduced onto the cathode and the deposit is peeled off for re-refining. Intelligent control handles the current so the deposit does not splash or over-electrolyse.
One to four heads
The same cell scales by head count, so a workshop running one plating line and a plant running four can both be matched without changing technology.
Works on the dilute streams
Plating solution, drag-out tank, strip solution, plating rinse waters, iodine and iodide etching solution, e-waste stripping solution and spent photographic developer are all named applications.
Residual silver below 20 mg/L
On spent fixer, the published figures are a recovery rate of 98 percent or better with residual silver in the treated liquid below 20 mg/L, which is inside environmental discharge standards.
PP tank, replaceable electrodes
Acid and alkali resistant throughout, modular so electrodes can be swapped and the cell cleaned, with a continuous operating life described as over eight years.
Applications
Where It Is Used

FAQ
Precious Metal Electrolytic Recovery Machine Questions
How pure is the metal it produces?
99.8 percent, per the source description. Recovery rate is 99 percent or better for gold and silver, and 90 percent or better for copper, nickel, platinum and palladium.
What power does it draw?
300, 350, 400 or 500 W depending on configuration, at 220 V or 380 V. Tare weight 50 kg.
Does it work on spent fixer solution?
Yes, and that is one of the best-documented cases. Waste fixer typically runs 3 to 6 grams of silver per litre, so 20 litres of solution yields roughly 80 grams of silver in one operation.
Does it need extra reagents?
On fixer, no. The spent fixer itself is the electrolyte; no additional reagent is added.
