Chat Online· This process does not result in gold that is 100 pure but it does eliminate the bulk of the impurities. The problem with this method is the release of the mercury vapor into the environment. Even if the equipment is used to catch the vapor some still can get into the atmosphere. Mercury also can get into the soil and water if it still is

Chat Online· Mercury processingMercury processingExtraction and refining 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.
