How to Test for Gold Ore | Sciencing
Start with the 14K gold wire. Streak the wire across the plate beside the gold sample. Make sure the lines do not intersect. Apply aqua regia to both streaks. The aqua regia will react—bubble and fizz—if it contacts gold. The acid will turn the same color when the purity of the ore sample matches the test wire.

9 Easy Ways to Tell if a Rock Contains Gold From A Geologist
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. This method helps you guess if the rock might contain gold, as gold is much denser than most common materials. If the density is much higher than that of common ...

Easy Ways to Extract Gold from a Rock (with Pictures)
Put the rock powder in a mining pan. A mining pan has holes in the bottom of it like a colander. Because gold is heavy, it will sink to the bottom of the mining pan even while it's submerged in water, while the other minerals wash away. Pour a layer of rock powder onto the mining pan so you can extract the gold pieces.

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.
