So how do you use mercury to extract the gold from gold-bearing rock? When you mix the finely powdered gold-bearing rock with some mercury, the gold within the rock dissolves, to form what's called a gold amalgam. The next step in the process is to separate the gold amalgam from any 'unreacted' mercury.
