The lifecycle of a gold mine. People in hard hats working underground is what often comes to mind when thinking about how gold is mined.

Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well
Historically, mercury has been widely used in placer gold mining to form mercurygold amalgam with smaller gold particles, thereby increasing the rate of gold recovery. In the 1960s, largescale mercury use stopped. In artisanal and smallscale gold mining (ASGM), however, mercury is still used, often clandestine, gold prospecting.
