Mercury Amalgamation in ASGM
The Largest Mercury Pollution Source
The largest source of mercury emissions of anthropogenic activity ever made on the earth is artisanal and small-scale gold mining known as ASGM where mercury is used in the traditional method of amalgamation to extract gold from the ore rock. ASGM activities are also sources of social problems, such as land tenure issues, social instability such as migration, and conflict between residents.
Amalgamation process and Hg pollution
The main reason for using mercury during the amalgamation process is to extract the gold from ore rock. But Hg pollution such as atmospheric hg pollution happened during each process.
