One tromol grinded 40 kg of ore for 4 h. After 4 h passed, milling paused and added approximately 0.5 kg to 1 kg of mercury into the tromol then grinding was continued for 1 h. Oneunit of milling processing 400 kg of gold ore before the amalgam was taken.
Trace element concentrations in shallow marine sediments of the Buyat-Ratototok district of North Sulawesi, Indonesia, are affected by submarine disposal of industrial gold mine tailings and unregulated dumping of tailings and wastewater from small-scale gold mining using mercury amalgamation. Industrial mine tailings contained 590–690 ppm arsenic, 490–580 ppm antimony, and 0.8–5.8 ppm
Gold processing activities which use mercury in the amalgamation process in Poboya goldmine is the main source of pollutant of the soil around the mine. Km0 = The first location was an area 0 km from the center of the gold mining area (active tromol location; contamination level: highly contaminated), Cluster II: Km1 = The second location
