ELE-AUEX electrolytic recovery systems extract precious metals from circuit boards, CPUs, gold-bearing ore, copper ore, plated parts, plating wastewater, photographic film, fixer solution and other metal-bearing scrap — using eco-friendly reagents in place of sodium cyanide and aqua regia, with a patented high-frequency pulse power supply and iridium-tantalum coated titanium anodes, to recover high-purity gold, silver and cathode copper.
Five models cover everything from a first bench-top setup to a doubled-capacity production unit. Prices are ex-works from the current ELE-AUEX price list — freight to your country is quoted per order.
The all-round machine: gold, silver, copper, nickel and palladium from e-waste leach solutions and ore.
Twin-cylinder version of the A350 — roughly double the throughput, around 2 tonnes of solution per day.
Entry-level multi-metal machine with graphite anode — the lowest-cost way to start recovering.
Dedicated copper extraction machine for boards, wires and copper-bearing scrap.
Refines 925 silver up to 99.99% purity. Up to four kits can be fitted to a single A350.
Modules are independent and combinable — link several machines with leaching tanks into a full line sized to your daily tonnage.
All models: 220 V / 50 Hz, PLC touchscreen control with 3-stage automatic timing, fumigation-free plywood export case. Machines ship from Shenzhen, China.
ELE-AUEX specialises in the design and manufacture of low-voltage electrolytic extraction equipment for precious metals. From our factory in Huizhou, Guangdong, we build electrowinning systems that recover gold, silver, copper, platinum and palladium from process solutions — working in a low-voltage electrochemical environment that is efficient, safe and environmentally friendly, with responsible disposal of end waste solutions.
Our equipment serves the electroplating, PCB and electronics recycling, jewellery, photovoltaic and mining industries — anywhere precious metals are dissolved in solution: electronic waste, gold and copper ore, plated parts and plating wastewater. The systems are modular, from a single unit for a workshop to multi-tank automated lines for factories, and our eco-friendly reagents replace sodium cyanide and aqua regia in the leaching stage.
We don't just sell machines. Every unit is tested before shipment, and we teach the complete process — leaching, electrolysis and refining — with online technical support after delivery. Today, customers across the Middle East, India, Europe and Southeast Asia recover precious metals with ELE-AUEX systems every day.

The A350 runs on a patented high-frequency pulse (PWM) power supply. That single difference decides how cleanly metal plates out of a dilute solution.
Short, controlled pulses with rest intervals between them.
Constant current, the way cheap copies are built.
The selective agents strip the precious-metal plating off the material and into solution — this is the same material before the leach and after it. Real workshop photos.

Selective agents are what make the process work without cyanide — they are eco-friendly reagents that meet environmental requirements.
Dissolves gold only, leaving base metals behind. 1 kg of agent recovers roughly 150–200 g of gold. Positioned as a sodium-cyanide replacement; low hazard class (eye/skin irritant — SDS available).
Shelf life about 1 year; store dry and away from light.
Selective leach for silver-bearing material. Working solution is held at pH 10.5–11 for stable deposition.
Titanium-alloy refining kit that takes 925 silver up to 99.99% purity. Up to four kits can be fitted to a single A350.
Full consumable list and SDS documents are sent with every quotation.
50% deposit to start production, balance before shipment. Discounts and closing terms are agreed one-to-one on WhatsApp.
Standard machines about 4–7 working days; A350 Plus around 20 days. Custom lines are scheduled per project.
12 months: free repair and parts for non-man-made faults. Online technical support group, including the technical director.
Fumigation-free plywood cases, shipped worldwide from Shenzhen. Send your city and James will quote the freight.
Tell James two things — gold or silver first, and what your feedstock is — and he will point you at the right model. Most buyers processing mixed e-waste start with the A350; the A330 suits a smaller budget, and the A350 Plus is for buyers who already know their daily volume.
No. The selective agents are positioned as a sodium-cyanide replacement and carry a low hazard classification (GHS07 — eye and mild skin irritation). The full safety data sheet is available with any quotation.
Machines ship worldwide from Shenzhen in plywood export cases. Freight depends on the model and your destination city — message James your city and he will include the freight in your quote.
A 12-month warranty (free repair and parts for non-man-made faults), an operation manual, setup guidance, and an online technical support group that includes the technical director.
Most questions are answered fastest on WhatsApp — send a photo of your feedstock and your city, and you will get a straight answer on suitability, price and freight.
