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