    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.
