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.
Any amalgamated metals such as gold will be left behind in the retort. The alternative for small amounts of mercury is to use nitric acid to separate it. Gold is not soluble in nitric acid, but mercury is. Use dilute nitric acid rather than more concentrated forms.
The gold should slip down into the smelting vessel. After this occurs, you can cool and remove the gold from the smelting vessel and also remove the slag as well. It's common at this point to refine the gold through a separate refinement process to ensure a high level of purity.

In some cases, you are correct. If gold is mixed evenly in the alloy and at a low enough concentration, you can use plain nitric acid to dissolve away impurities.
