Mercury Retort for Sale
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. This process allows you to reclaim and reuse the mercury.

Mercury processing
Mercury processing - Extraction, Refining, Recovery: The pyrometallurgical extraction of mercury from its ore is essentially a distillation process. When heat is applied to the sulfide ore in the presence of air, oxygen combines with the sulfur to form sulfur dioxide, and the metal is liberated at a temperature above its boiling point. The gases are then passed …
