    Reducing Mercury Pollution From Artisanal Gold Mining In

    Jun 02, 2020 Artisanal and small scale gold miners in the Peruvian Amazon use liquid elemental mercury to extract gold from soils and sediments. The mercury binds to the gold to form an amalgam, which is then extracted by burning, creating gaseous mercury that enters the atmosphere.Mercury and gold are combined together to form a gold mercury amalgam. Gold is then extracted by vaporizing the mercury. The remnants of this amalgam then percolate into the soil or flow to the nearby environment, eventually finding their way into water streams. This poses a great danger to local communities and the environment in gold mining.
