How to Test a Rock for Gold | Sciencing

Placer Gold. In the pan, gold stays near the bottom or along the edge of a ridge because it is heavier than other rocks. It is malleable, which means it can be dented, and it has a brassy yellow color. This type of gold may even have quartz or other mineral material still attached to it.

Gold mining - Wikipedia

Historically, mercury was used extensively in placer gold mining in order to form mercury-gold amalgam with smaller gold particles, and thereby increase the gold recovery rates. Large-scale use of mercury stopped in the 1960s. However, mercury is still used in artisanal and small-scale gold mining (ASGM), often clandestine, gold prospecting.
