Reactivity of Mercury from Gold Mining Activities in
MERCURY IN MINING OPERATIONS Mercury (Hg) is the seventh metal of antiquity and has been used for more than 3500 years. Romans used elemental Hg as an amalgam to separate gold from other materials and to coat gold onto copper (1). Gold extraction using amalgamation was widespread until the end of the first millennium.

Exposure and toxic effects of elemental mercury in gold
Traditional gold mining, using metallic mercury (Hg(0)) to form gold amalgam, followed by burning to remove the Hg(0), is widely used in South America, Africa and Asia. The gold is sold to merchants who burn it again to eliminate remaining Hg(0). In Ecuador, 200 gold miners, 37 gold merchants and 72
