3) Broken ore is put into the mills. Mercury is added to the mill to bind the tiny gold particles together. The mercury–gold amalgam is heavier than crushed rock particles and sinks to the bottom of the mill. Gold particles that don’t come into contact with mercury in the mill can be caught on a mercury-covered plate at the runoff.

Mercury-dependent artisanal and small-scale gold mining (ASGM) is the largest source of mercury pollution on Earth. In this practice, elemental mercury is used to extract gold from ore as an amalgam. The amalgam is typically isolated by hand and then heated—often with a torch or over a stove—to distill the mercury and isolate the gold.
