Mercury processing Extraction and refining Britannica

Extraction and refining Pyrometallurgy. 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 Ushaped tubes to condense
