Mercury Usage in Gold Mining and Why It Is a Problem

Jul 22, 2019· 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
