99.99% High Purity Gold Electrolysis From Gold Wet Way Purification
we specialize in new technology research and development, new machine research and development, technology promotion, production process and workshop design of various precious metal smelting, electrolysis and environmental protection, as well as all-round service businesses such as design and manufacturing of various professional customize equipment, overall workshop equipment installation, operator training, organization and guidance of trial production
Charactors:
(1) Casting anode plate: the crude gold raw material with 99% gold content is melted into the medium frequency smelting furnace and cast into a gold electrolytic anode plate.
(2) Electrolyte preparation and waste electrolyte recovery: gold electrolyte is prepared by dissolving pure gold in aqua regia and diluting it with hydrochloric acid aqueous solution.
(3) Electrolysis: hang the anode plate into the gold electrolysis cell and start the gold electrolysis equipment for electrolysis.
The company's high-efficiency gold electrolysis unit (as shown in the figure) is developed based on years of experience in gold refining projects and customer suggestions. It adopts integrated and integrated design. The whole machine includes a single electrolytic cell, circulating pump, rectifier power supply, automatic electrolyte replenishment system, electrolytic flue gas condensation recovery system, electrolyte temperature, voltage, current The copper bar temperature intelligent monitoring system, the rectifier power supply is closed separately, isolated from the acid gas in the workshop, and has a long service life.
With a number of domestic patents and advanced technology, it has the following advantages:
① The product quality is stable and can meet the gold ingot standard of au99.99 (grade I) of Shanghai Gold Exchange; it can also produce gold ingots with purity of 99.99% according to the special needs of customers;
② Low production cost: about 0.02 yuan / gram gold;
③ The electrolysis adopts AC / DC superimposed power supply, which can effectively inhibit the generation of silver chloride on the gold anode and make the anode plate electrolysis more thorough;
④ High current density electrolysis technology; cathode current density up to 1200A / m2, high production efficiency;
⑤ The electrolytic cell is designed with a transparent closed smoke cover to prevent smoke from escaping, which is easy to operate and beautiful;
⑥ A flue gas condensing device is set. Due to the high temperature (60-70 ℃) required by the gold electrolysis process, the flue gas condensing device can condense the reflux volatile electrolyte to avoid the loss of gold;
The main material of the equipment is high performance polypropylene material, adding anti-aging agent to the material, which greatly prolongs the service life of the equipment. The whole bracket material is PPH, and the corrosion resistance is very strong; the cathode and anode conductive bar material is titanium coated copper with excellent conductivity.
This set of gold electrolysis unit is designed with PLC automatic operation system, controlled by touch screen, and has the function of electrolytic parameter storage. When the electrolytic voltage, current and copper bar temperature are abnormal, the rectifier power supply can be directly interlocked to stop. The whole set of equipment is simple, safe and convenient.

gold refining electrolysis processgold refining electrolysis processFor rough gold with a gold content of less than 95%, initial treatment involves powdering. After powdering, the powdered gold is subjected to acid leaching using nitric acid to remove impurities such as silver and copper. The filtered solution is then processed for silver recovery. The insoluble gold powder undergoes aqua regia dissolution; insoluble residues from this process are subsequently sent for silver recovery. A secondary refining process is applied, where once reduced, 99.99% pure gold is cast into granules or ingots. The refined gold returns to the aqua regia process for further dissolution. After drying, the refined gold is formed into granules and then cast into standard gold ingots.
For raw materials with a gold content of 95% or higher, they can be directly smelted in a medium-frequency furnace, cast into ingots, and then subjected to high-efficiency electrorefining using a gold refining electrolysis system. The refined gold is then cleaned, dried, and finally cast into finished gold ingots.

gold platinum recycling equipmentgold platinum recycling equipment(1) Dissolve in aqua regia:The residues are placed in a reaction container, and hydrochloric acid (HCl) and nitric acid (HNO3) are added in a 3:1 ratio by mass. The mixture is heated to a temperature between 60°C and 80°C using steam, allowing gold and platinum to dissolve in the solution. After the reaction is complete, the solution is filtered and washed, with the filtrate being sent for platinum extraction.
(2) Based on the differences in the reaction processes of platinum and gold, a separation is performed:Ammonium chloride (NH4Cl) is added to the filtered solution to precipitate platinum, while gold does not form a precipitate at this stage. The solution is then filtered again, and the resulting ammonioplatinum chloride is calcined to produce crude platinum, which contains gold in a high-temperature solution that is then sent for gold reduction.
