Oat gold, fine gold, micron gold (micros), and gold dust are all terms used for the smallest forms of gold. These minute particles get lodged under rocks and pebbles and collect on the top of bedrock. They originate from lode gold upstream that breaks apart and is washed downhill. The farther the gold tumbles, the smaller the fragments get.

The chemicals used include mercury and iron. ... This is a relatively new process and refines gold by separating it from other metal elements using an electrolytic cell ...
With a minimum of equipment, the beginner gold prospector can separate gold flakes and nuggets from the surrounding strata in a nearby stream. The supply of gold is virtually endless, as erosion constantly causes hidden gold to be brought to the surface where it is free for the taking. All you have to do is find it.
The density of salt is 2.16 g/cm³ while the density of sand is 2.65 g/cm³. In other words, sand is slightly heavier than salt. If you shake a pan of salt and sand, the salt will eventually rise to the top. A similar method is used to pan for gold, since gold has a higher density than most other substances and sinks in a mixture.
Fig. 2. Fine gold in sand. There are various methods that are used to mine gold dust but very few have been successful in completely recovering all the gold dust contained in refractory ores. A majority of the methods employed in the extraction of gold dust essentially use water to separate the gold particles from the other materials.
