Extracting gold from rock - OpenLearn - Open University
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.

Gold processing - Mining, Gravity, Amalgamation Cyanidation
Elemental gold (and silver as well) is soluble in mercury, so that, when particles of the metal are brought into contact with a fresh mercury surface, they are wetted and dissolved, forming an alloy called amalgam. This phenomenon is exploited for the recovery and concentration of fine particulate gold or silver.
