How Is Gold Purified? | Sciencing

Apr 24, 2017 · After a sample of treated impure gold has been tested in a lab for purity, the gold is melted in a furnace, then chlorine is bubbled through the liquid. The chlorine attaches to elements in the gold that then become solid and move toward the top of the furnace. They are skimmed off. Electrolysis is ultimately used to purify the gold.
