Electrorefining – Electrolytic Gold Recovery | Gold Refineries

Gold purity is typically 99.999%. Once the anode has been dissolved, the gold cathode can be removed, rinsed and melted into ingots. Unfortunately, the entire process can take a couple of days. For economical refining; often a different refining process, known as the Miller Chlorination Process, is used to separate gold to a purity of about 99.5%.
