The chemical refining of gold usually involves dissolving crude gold in aqua regia or a sodium chlorate-hydrochloric acid solution. Sodium sulfite or other reducing agents are then introduced for potential-controlled reduction, producing 99.99% pure gold.

Product Introduction of Gold Extraction Machine:

Swirl electrowinning is a wet metallurgical technology used for the selective electrowinning and extraction of gold. It is particularly suitable for the selective electrolytic separation and purification of valuable metals from low-concentration or complex-composition solutions in the metallurgical industry, as well as for the recovery of gold from wastewater.

Advantages of Gold Extraction Machine:

1)、Capable of processing low-concentration metal solutions with higher production efficiency compared to traditional electrolytic technologies. It can enrich valuable metals across a wide range of concentrations, from fractions of a gram per liter to hundreds of grams per liter, especially excelling in copper-nickel and copper-silver separation.

2)、Strong adaptability to pollutants in solutions, enabling the extraction of high-purity gold from impure solutions.

3)、Capable of extracting multiple metals with selective electrolysis, and able to produce cathode products in different forms (plates or metal powders) depending on solution concentration.

4)、Modular equipment design with simple operation.

Model parameters of gold extraction machine

Current: Single tank designed for 100A, voltage 5V.
Each small tank can process approximately 200L of solution. Single or multiple tanks can be selected based on production requirements, with processing speed varying according to concentration. 

Result of Gold Extraction Machine:

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.
