mercury processing - Extraction and refining | Britannica

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 through a series of U-shaped tubes to condense the mercury vapour to the liquid phase.
