Electrowinning Gold is a method of “extracting” gold from a solution using electric current. In a solution containing gold, gold exists in the form of charged particles. When a stable direct current is applied, these gold ions move towards the negative electrode under the influence of the electric field, acquire electrons on the surface of the negative electrode, and turn back into solid metallic gold, which “grows” layer by layer on the negative electrode plate. This process usually requires long-term stable operation under low voltage and high current conditions, thus placing high demands on the stability and continuous working capability of the direct current power supply.
The entire gold extraction process is actually quite coherent:
1️⃣
ore or gold-bearing waste is soaked in a solution such as cyanide, allowing the gold to dissolve from the raw material into the liquid and complete leaching.
2️⃣
this gold-bearing solution is poured into an electrolytic cell and a direct current is applied, causing the gold to continuously deposit on the cathode plate.
3️⃣
the gold sludge deposited on the cathode plate is scraped off, dried, smelted, and finally cast into gold ingots or gold particles. This allows for efficient gold recovery.
This method is very popular across multiple industries, especially in gold mining, “gold recovery” from old circuit boards, and various metal processing plants. Its greatest advantage lies in its ability to truly “extract” gold. The equipment operates very stably and can work continuously. Even for solutions that do not appear to be “rich” in gold, as long as slow collection and repeated extraction are persisted, the total cost is quite cost-effective in the end.
To truly commence operations, a high-quality DC power supply is crucial. This power supply must fulfill several stringent requirements: the output DC power must be as stable as possible, the current must be as pure as if it had been filtered, and the machine itself must be durable. Only by meeting these requirements can the gold plating be uniform and aesthetically pleasing, the entire process be well-controlled, and the equipment operate stably for an extended period.
