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.
