Combine the mercury sulfide (HgS) with the powdered rock using a metal rod to stir the minerals together. Keep stirring until they’re mixed well. Watch for the gold to melt out of the rest of the rock. The mercury and gold will react with each other and form a liquid amalgam. See also what is the relationship between surface tension and cohesion.

Gold deposits can be grouped into two primary classes: placer deposits, where the gold is exposed from weathering and erosion, and hard rock, where the gold is still trapped within the host rock. Gold recovery methods for these two types of deposits vary greatly from simple panning to a complex network of grinding, chemical leaching, gravity concentration and more.
