  • Mercury Usage in Gold Mining and Why It Is a Problem

    22/07/2019· The mixture of gold and mercury is then heated to a temperature that will vaporize the mercury, leaving behind the gold. 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
