The gold mining life cycle Mining for schools

The gold mining life cycle. Step 1 Openpit gold mining also takes place in South Africa. This is a mining technique which excavates at the surface to extract ore. The mine is open to the surface for the duration of its life. The gold particles, extracted in this process, attach themselves to the carbon. The next step in the process

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.
