Gold remains one of Ghana's major export commodities, with its mining largely done on a small-scale level. The process at the small-scale level involves dissolving the gold ore in mercury then heat-vaporizing the mercury, although this is dangerous.
Small-scale mining operations in Asia, Africa and South America still use mercury to mine for gold. It's illegal and highly toxic to the workers and the environment and it's now estimated to be responsible for one-third of mercury pollution worldwide. 2

Small-scale gold miners are in contact with mercury in different stages of the mining process, notably amalgamation, separation of the amalgam, removal of excess mercury and burning the amalgam. Exposure to mercury may cause a wide range of symptoms including chemical bronchiolitis and
