The method of electrolytic pure gold

Electricity is a commonly used method for purifying gold. Below is a basic method of electrolytic pure gold:
Prepare electrolyte: First, you need to prepare an electrolyte. A commonly used electrolytic solution is cyanide solution and usually uses sodium cyanide or potassium cyanide. Add an appropriate amount of sodium cyanide or potassium cyanide into the distilled water and stir well to make an electrolyte.
Prepare electrolytic grooves: Fill the electrolytic groove and fill the charging solution and install the cathode and anode. The cathode is usually stainless steel plate, and the anode can be metal blocks or metal nets.
Prepare golden samples: Place the golden samples that need to be purified on the anode.
Electrolytic: Connect the power and turn on the current. Through electrolytic effects, gold ions (AU+) will be oxidized into gold ions (AU3+) on the anode, and then gold ions will be separated in the electrolyte.
Deposited pure gold: The free gold ions will be deposited on the cathode to form a pure gold layer. Over time, the impurities on the golden sample will gradually be removed, while the pure gold layer gradually thickens.
Stop electrical: When the pure gold layer reaches the required thickness, stop the current and remove the pure gold layer on the cathode.
It should be noted that this electrolytic method requires specific equipment and operating technologies, and it also needs to strictly abide by relevant safety regulations because it involves a toxic cyanide solution. This purification method is recommended to perform such purity in professional guidance or laboratory environment.

Of course, I can continue to provide more information about electrolytic and pure gold.
Pure again (optional): If you need a higher purity gold, you can use the removed gold layer to be refined and purified again. This process can be repeated multiple times to achieve the required purity.
Refining: The metal after electrolyte is purely contains some impurities. In order to further improve the purity, other methods can be used for refining. Common refined methods include oxidation, cyanide, and solvent extraction.
Separation and recovery: In the process of purification, some waste liquids or exhaust gas may be generated, and these need to be treated and recycled. The waste liquid can be treated by chemical methods to recycle residual gold or other valuable metals.
It should be noted that the purification of golden electrolytic is a complicated process that requires certain professional knowledge and technology. In addition, due to the high value of gold, the purity process also needs to comply with relevant laws and regulations to ensure legal and security operations.
The best way is to make gold electrolytic purification under the guidance of a professional laboratory or experienced professionals to ensure the safety and effect of the operation.
