PRS Gold Electrolytic Refining Equipment
Our gold electrolysis Refining Equipment is widely applicable to mining enterprises, gold processing workshops, and scrap gold recycling facilities. It covers small to large-scale production needs, with daily pure gold output ranging from 2.5kg to 20kg, perfectly matching different production scales and scenarios.
1. Overview
Sichuan Precision Technology (PRS) specializes in R&D and manufacturing of gold electrolytic refining equipment, a professional device that uses electrolysis to purify crude gold (gold content ≥95%) to high-purity standards. Adopting advanced hydrometallurgical technology, the equipment takes crude gold as anode, titanium sheet or pure gold as cathode, and chloroauric acid solution as electrolyte. By introducing DC or AC-DC superimposed power supply, crude gold dissolves at the anode and pure gold precipitates at the cathode, realizing efficient and precise gold purification.
2. Core Advantages
Super High Purity Output:
The refined gold can stably meet the Au99.99 (Grade 1) standard of the Shanghai Gold Exchange. Secondary electrolysis is available to produce 99.999% high-purity gold ingots according to customer needs.
Low Production Cost:
The comprehensive cost is only about 0.02 yuan per gram of gold, significantly reducing the operation cost for enterprises compared with traditional refining methods.
Efficient Production Capacity:
Equipped with high current density technology (up to 1000A/M²), the electrolytic gold refining system accelerates electrolysis reaction, shortening the production cycle and improving overall efficiency.
AC-DC Superimposed Power Supply:
Effectively avoids the generation of silver chloride on the gold anode, ensuring thorough electrolysis of the anode plate and improving gold recovery rate.
Intelligent Automatic Control:
Realizes automatic control of electrolyte temperature, titration fluid supplement, and self-circulation of electrolyte, reducing manual operation and ensuring stable product quality.
Eco-Friendly & Safe Design:
Equipped with transparent closed smoke hood and flue gas condensation device, which condenses and reflows volatile electrolyte to avoid gold loss and environmental pollution. The working environment is clean and easy to operate.
Durable High-Quality Materials:
The main body is made of high-performance polypropylene with anti-aging agents, and the overall bracket is PPH material with strong corrosion resistance. The cathode and anode conductive strips are titanium-clad copper, ensuring excellent conductivity and long service life.
Compact Structure:
The whole set of equipment covers only about 4m², saving workshop space and reducing installation and layout costs.

Frequently Asked Questions
Q1: What raw materials are suitable for PRS gold electrolytic refining equipment?
A: The equipment is mainly suitable for crude gold with a gold content of ≥95% , including crude gold ingots extracted from gold mines, scrap gold (such as gold jewelry waste, electronic component scrap containing gold), and primary refined gold with low purity. It is not recommended to process raw materials with gold content lower than 95% directly, as this will affect refining efficiency and increase production costs.
Q2: How to ensure the stable output of 99.99% high-purity gold?
A: Three core conditions need to be met: first, control the raw material purity (≥95%) to reduce impurity interference; second, maintain the electrolyte parameters (acidity, temperature) within the range recommended by PRS, and supplement new electrolyte regularly; third, use the matching AC-DC superimposed power supply of the equipment to avoid uneven electrolysis. Following the operation manual can stably achieve 99.99% purity, and secondary electrolysis is available for 99.999% high-purity requirements.
Q3: What should I do if anode passivation occurs during electrolysis?
A: Anode passivation is usually caused by insufficient electrolyte acidity, low temperature, or excessive current density . You can take three measures: first, appropriately increase the concentration of hydrochloric acid in the electrolyte to improve acidity; second, raise the electrolyte temperature to 40-60℃ to enhance conductivity; third, reduce the current density appropriately to avoid excessive reaction intensity. The equipment’s intelligent control system can monitor related parameters in real time to remind you of adjustments in advance.
