The basic purpose of this program is to promote better mining methods and practices, and thus curb health threats and pollution caused by gold mining activities.Mercury is used in ASGM to concentrate gold by forming a mercury-gold amalgam, which is then heated to drive off the mercury into the atmosphere, leaving only the gold. This process is favored by small-scale miners over other methods of gold extraction because it is inexpensive, accessible, simple to use, and allows miners to produce gold.
