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.

A PRACTICAL GUIDE

1. Gold can represent an excellent method of transferring wealth to rural communities: small-scale producers often get 70% or more of international prices, even in remote areas. This is much higher than other products such as coffee, bananas, etc. 2. Artisanal and small-scale gold mining (ASGM) needs to be brought into the
