How Is Mercury Used to Purify Gold? | Sciencing

Apr 24, 2017· Miners submerged their ore in mercury, which would take on the gold but not the other impurities. The mixture of mercury and gold would then be recollected and heated until the mercury boiled away. A simple still like those used to make alcohol would draw away the vaporized mercury, possibly collecting it for reuse, leaving mostly pure gold.
