Mercury Retort – High Plains Prospectors

The purpose of the retort is to separate the gold from the mercury components of the gold amalgam. By applying heat to the amalgam the mercury is burnt off as a gas, which passes along the pipe to re-condense as a liquid. The gold remains in the distilling chamber of the retort, while the mercury is collected at the discharge end in liquid form.
