Eventually, the hydrogen in the star's core runs out, and gravity causes the star to collapse. What happens next depends on the star's mass, but gold is formed when the collapse creates a massive shockwave. During the explosion, a tremendous amount of energy creates heavy elements through the rapid neutron-capture process.

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.

First, weigh the rock on a food scale and record its weight. Next, fill a measuring cup halfway with water and note the level. Gently place the rock in the water and see how much the water rises. This rise tells you the rock's volume. Finally, divide the rock's weight by its volume to calculate its density.

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.
