Mercury. We used mercury to get the gold out of the powdered rock. Gold, like most minerals, can be 'dissolved' in mercury to form what's called an amalgam. An amalgam is a physical mixture, a type of alloy. This is a comparatively straightforward way of separating the gold from the rock, as the rock remains untouched by the mercury.

Extraction. Quartz is extracted from open pit mines. Miners only use explosives on rare occasions when they need to expose a deep seam of quartz. The reason for this is that although quartz is known for its hardness, it damages easily if it is suddenly exposed to a change in temperature, such as that caused by a blast.

Gold, being much denser than rock, settles at the bottom. In the 1800s, panning was one of the simplest forms of placer mining. Hard rock mining involved miners digging tunnels deep into the earth to reach the quartz veins. The extracted quartz rocks with embedded gold were then ground into a fine dust in stamp mills.
