Gold mining

Historically mercury was used extensively in placer gold mining in order to form mercury-gold amalgam with smaller gold particles and thereby increase the gold recovery rates Large-scale use of mercury stopped in the 1960s However mercury is still used in artisanal and small-scale gold mining (ASGM) often clandestine gold prospecting

Mercury Use in Small

Although large-scale gold mines have adopted other methodologies to reduce their mercury use sometimes mercury may be generated as a byproduct in those types of mines as well How Does the Process Work? When the ore is exposed to mercury mercury will bind to the gold and form an amalgam making it easier to separate the gold
