Stamp mills used mercury to extract gold from the crushed rock, increasing the yield. Crushed gold ore was combined with liquid mercury. The gold stuck to the mercury and this slurry was then boiled, evaporating the mercury, leaving behind the gold. Some mercury boiled off into the air, and some was recaptured and used again.
