May 19, 2009 It can be done economically using ore with less than one gram of gold per ton (depending, of course on the Gold Price). When lower-cost extraction is needed, heap leaching is used. Ore is piled in a lined, prepared area and then treated with dilute cyanide.

Apr 16, 2019 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.
