Amalgamation, which uses mercury and gold particles to form an amalgam, is often used in small-scale mining operations. This type of ore is generally processed by flotation, which concentrates the gold in the non-ferrous ore concentrate and then recovers the gold during the smelting process. Gold can be obtained by cyanidation from gold …

The Mercury Problem in Artisanal Gold Mining. Mercury-based artisanal and small-scale gold mining (ASGM) causes more mercury pollution than any other human activity. 1 In this practice, mercury metal is used to extract gold from ore as a stable amalgam. The amalgam is then heated to evaporate the mercury and isolate the gold.
