The FEL14 closed-type electrolyzer is designed for regeneration of the leaching solution for the extraction of precious metals from solutions of iodine-iodide, chlorine-chloride, cyanide, thiourea, etc.  

 Electrolyzers have anode and cathode chambers separated by a ceramic membrane. The solution from the leaching reactor, enriched with noble metals, enters the cathode chamber. In the cathode chamber, the pH of the solution, rising to ??????, generates iodide and metals deposited on the carbon material. From the cathode chamber, the iodide solution enters the anode chamber, where iodine is generated. Iodine reacts with iodide to form a solution of KI3. The regenerated solution is sucked off by a pump and then enters the reactor for leaching the next batch of ore.

Can operate as a separate unit or in a general leaching system

Comes with pump and regulated power supply

​

Electrolyser FEL10 open type with titanium cathode

designed for acid-free refining of metallic gold from cast anode  or granulated gold

 

Can also be used as a portable gold, silver and platinum group metal analyzer in the field, for regeneration oxidizing leaching reagents.

​

Know-how - Flexicone leaching technology, which ensures up to 100% recovery of gold and precious metals from alloys. The electrolyzer is recommended for jewelers, laboratories, hydrometallurgy researchers, small and large mining companies. This reactor is designed for electrochemical purification technology of gold, silver and platinum metals, but can also be used for other chemical processes. The main leaching reagent is NaCl (table salt) with a small amount of starting salt added. Precious metals will precipitate with the addition of non-hazardous salt. A complete description of the process is provided upon purchase of the Electrolyser.

Compared with similar salt system from other suppliers, ours is suitable for both solid molten metal anodes and granular material or jewelry, and is also suitable for computer parts and other electronic scrap using our anodes. (Information about the unique electronic scrap recycling process and dissolution of gold plating material will be provided when purchasing the system.) 100% gold recovery. This system includes a very easy to use test kit that detects as little as one part per million parts of solution, ensuring that no dissolved gold is lost. When refining platinum group metals, we also supply a test solution to determine one part palladium per million parts solution. Even if you have no refining experience, the metals produced by our electrolyser are 99.95% pure or higher. Safe + odorless. No acids, harmful fumes or toxic chemicals. Easy to use. No experience required. The kit includes both video and written instructions. Universal. Purifies low-grade gold, silver, platinum group metals from alloys, ore concentrates and gold mining concentrates. Effective. This dual capacity device can handle batches up to 1kg. It only takes about 60 minutes to refine 30g of gold. The gold plating can be removed without dissolving all the metal.
