Use refined gold; For 10K and more gold: Melt your gold with copper, or with gold-filled items to make it 6K to 8K, and cast an ingot; Place gold ingot into the unit, fill the unit with electrolyte and turn on power supply; 12-24 hours later, remove anode section, wash the gold with water; Remove refined gold from anode section; Use refined gold

Gold electrolysis is the system which obtains gold mud from carbon by desorption and electrowinning. There are two process ways. One is in normal temperature and pressure desorption and electrolysis. Another …

Platinum remains in solution until it reaches double the amount of the gold present. The salts in the solution are necessary for a coherent deposit of gold. Some gold is deposited with the anode mud, and this is due to the formation of aurous chloride, which at once splits up in the presence of water to auric chloride and metallic gold.

Another element that is isolated by electrolysis is aluminum. Aluminum formerly was a difficult metal to isolate in its elemental form; in fact, the top of the Washington Monument has a 2.8 kg cap of aluminum metal, which at the time—1884—was the largest piece of elemental aluminum ever isolated. ...

If your gold is unrefined, your best option may be to ship it to a refiner. These processes may be challenging and cost-prohibitive for you. Another issue is that if you try to refine your own scrap, you may only recover the gold and not the other precious metals that may be present, such as silver and platinum.
