Mining What Is Gold Mining How Is Gold Mined

2020 6 10ensp0183enspHistorically, 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.
