Product Description:
Gold electrolysis unit, suitable for refining gold with a purity of 92% or higher. Currently, our company offers standard models such as JQ-JDJ-5, JQ-JDJ-10, JQ-JDJ-20, JQ-JDJ-30, and JQ-JDJ-50, which can meet daily gold production capacities of 5kg, 10kg, 20kg, 30kg, and 50kg. Custom orders are also available.
Scope of Application:
Suitable for processing crude gold with a purity of 92% or higher, and can also be used to produce 99.999% high-purity gold from 99.95% pure gold.
Process Introduction:
1) Electrolyte Preparation: The gold is dissolved using a chlorination method, and then diluted to a specified concentration with an aqueous solution of hydrochloric acid to serve as the electrolyte.
2) Crude Gold Ingot Casting: Crude gold with a gold content of 95% or higher and gold powder after secondary reduction are smelted in a medium-frequency furnace and poured into a specially designed anode mold to cast gold anode plates.
3) Electrolytic Refining: Transfer the prepared electrolyte to the electrolytic cell, hang the gold anode plate in the designated position, and start electrolysis. Using a superimposed AC/DC power supply ensures a more thorough electrolysis.
4) Cathode Gold: After electrolysis, shut down the electrolysis, remove the cathode, and peel off and clean the gold deposited on it. After cleaning, dry, cast into ingots, mark, and store.
Equipment Advantages:
- Very stable product quality, reaching Au99.99 gold ingot standards; 99.999% purity gold ingots can also be produced according to special needs.
- Low production cost: approximately 0.02 RMB/gram of gold.
- Utilizes high current density electrolysis technology (1000A/m²), resulting in high production efficiency and an electrolysis cycle of 22 hours.
- Low gold content: 12-13L of electrolyte is used for 5kg/day gold electrolysis, containing 120-150g/L of gold, with a gold content of up to 2kg. 5. Transparent, enclosed fume hood provides a good working environment, is easy to operate, and has an aesthetically pleasing appearance. The entire set of equipment occupies approximately 5 square meters.
- Equipped with a flue gas condensation device. Because the gold electrolysis process requires relatively high temperatures (60-70℃), the flue gas condensation device can condense and reflux the volatile electrolyte, preventing gold loss.
- The main body of the equipment is made of high-performance polypropylene material, and the cathode and anode conductive parts are made of titanium-clad copper, offering excellent conductivity.
