How Does Gold Extraction Work?
Extracting gold is a multi-step process that can be approached in different ways depending on how a company is prospecting and mining its gold supply. For example, placer mining, which was popular during the 19 th-century gold rushes, relies on a gravity-separation extraction process. In these cases, water is used to separate gold particles ...

Extracting gold from rock | OpenLearn
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.
