Toxic chemicals used in mining

Toxic chemicals are used in the Flotation Process to separate the copper and molybdenumout of the milled powder. This Flotation process is the major extraction method atDuval/Sierrita mine because of the poor quality of the copper at this site. Some

Mercury Usage in Gold Mining and Why It Is a Problem

This process does not result in gold that is 100% pure but it does eliminate the bulk ofthe impurities. The problem with this method is the release of the mercury vapor into theenvironment. Even if the equipment is used to ch the vapor some still can get into
