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. We did this by squeezing the crude ...

Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.
Tin processing - Tin processing - Mining and concentrating: Vein deposits, such as those in Bolivia and the United Kingdom, usually occur in granite formations and are recovered by conventional underground hard-rock mining techniques. In deep mines, primary crushing equipment is usually located underground in order to reduce the ore to a manageable size before transportation to the surface.
