Advantages of the New Gold Electrolysis Unit

As a professional manufacturer of precious metal recycling equipment, we have developed a new-generation gold electrolysis unit with reliable performance, high efficiency and low consumption. This equipment is widely used in gold refining processes for precious metal recovery projects and brings remarkable economic benefits to our customers. Below are its core advantages:

1. Stable and superior product quality The unit delivers highly stable refining results. It can consistently produce gold ingots that meet the Au99.99 purity standard. For special industrial demands, the equipment is also capable of manufacturing high-purity gold ingots up to 99.999%. The finished gold products meet international precious metal standards and are suitable for downstream processing, trading and industrial applications.
2. Low operating and production cost Our electrolysis technology effectively cuts reagent consumption. The consumption of hydrochloric acid is only 150 liters per ton of refined gold. With low chemical input and less waste generation, customers can significantly reduce recurring production expenses while lowering chemical waste disposal pressure.
3. High production efficiency with high current density electrolysis Adopting advanced high current density electrolysis technology of 1200A/m², the equipment greatly improves refining throughput. The electrolysis cycle varies from 10 to 22 hours, adjusted according to the thickness of anode plates. Fast processing cycles help shorten production lead time and raise daily output capacity.
4. Minimal gold capital locked in electrolyte One outstanding feature of this gold electrolysis system is low gold inventory occupation inside electrolyte. For a daily gold production capacity of 50 kg, the system only needs 96 liters of electrolyte. The electrolyte contains 120–150 g of gold, and the maximum amount of gold tied up in the solution is only 14.4 kg. Less capital occupied by precious metal improves cash flow for refiners.
5. User-friendly structure and small footprint The unit is fitted with a transparent enclosed fume hood. It maintains a clean and comfortable working environment. Operators can clearly observe the electrolysis reaction status, making daily operation convenient. The overall layout is compact and elegant. The whole set of equipment only occupies about 5 m² floor space, saving factory workshop area.
6. Flue gas condensation system to avoid gold loss Gold electrolysis requires a working temperature of 60–70°C. The built-in flue gas condensation device condenses and recycles volatile electrolyte. It prevents electrolyte escape along with hot fumes, effectively reducing the loss of gold carried by vapor and improving the overall gold recovery rate.
7. Premium anti-corrosion and conductive materials The main equipment body is constructed from high-performance polypropylene, which offers strong acid resistance and long service life. Both cathode and anode conducting bars are made of titanium-clad copper. This composite material provides outstanding electrical conductivity, stable current transmission and excellent corrosion resistance in acidic electrolysis environments.
8. Intelligent PLC automatic control system for safe operation The gold electrolysis unit is equipped with a full PLC automatic operating system and touchscreen interface. Operators can control rectifier power switches, set current and voltage values, and turn on/off heating and circulation functions directly on the touch panel. Real-time monitoring is available for electrolysis voltage, current and copper busbar temperature. Once abnormal parameters are detected, the system will trigger interlock protection and cut off the rectifier power supply automatically to avoid equipment damage and safety risks. All electrolysis parameters can be saved in the system for real-time checking and historical review. Saved data supports process analysis and troubleshooting. The whole system is simple to learn and operate, ensuring safe, stable and continuous production.
