6 Easy Steps to Extract Gold from Rock
Step 6. Shake to Reveal the Gold. When the mining pan is fully submerged, shake it until you see the gold resting at the pan's bottom. While you do this, you will see the other particles start to drift away from the pan, mixing with the water. This makes it easy to see the gold better. Lift the pan out and remove any clear gold piece you see.
