The Process Of Gold Mining

Historically, mercury has been widely used in placer gold mining to form mercury-gold amalgam with smaller gold particles, thereby increasing the rate of gold recovery. In the 1960s, large-scale mercury use stopped. In artisanal and small-scale gold mining ASGM, however, mercury is still used, often clandestine, gold prospecting.
