    Mercury poisoning In artisanal and small-scale gold mining, mercury is often used to separate gold from other materials. When burned, the mercury in the gold-mercury amalgam evaporates, leaving just the gold. Although this is an effective method to extract gold, the poisonous nature of mercury also makes it a highly dangerous one.3.1. Mercury Amalgamation The use of mercury has become popular among small scale miners because amalgamation is known to efficiently extract fine gold particles from concentrates obtained by panning or sluicing operations. Gold alloys with mercury to form an amalgam from which the gold could subsequently be separated by evaporating the mercury.
