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

2003 A 1 One way is by panning since gold is heavier than most other substances you can swirl water just fast enough that the gold stays in the pan while the other substances wash out Or 2 You can put everything into an acid that dissolves other substances and doesn t dissolve gold Or 3
Spiral Panning Wheelsthese are an angled device that uses an exclusively designed motion to separate the black sand from the gold They basically work like a gold pan retaining fine gold with gravity and allowing lighter materials to wash out 3 Gold CubeThese separate out the gold in a very similar fashion as the sluices that are

If gold is physically bound to minerals it can sometimes be separated by the application of heat in a smelting operation At other times the only way to separate the gold is to immerse quantities of black sand in chemical bathsa process called wet chemical extraction
Panning Panning is a gold mining method that uses water to separate the heavy gold particles from the lighter materials in the ore When panning for gold you put your crushed gold ore in a wide pan and then add water to it You then swirl the pan around with the aim of removing the lighter materials along with the water
Submerge the unrefined gold in a mixture of nitric and hydrochloric acids This method will dissolve the ore and separate the gold from the impurities which can later be washed away The remaining substances will be just water and gold the latter having a purity level of more than 99 99 percent Dry this residue until only gold powder remains
Since gold is a large specific gravity mineral with a specific gravity of 19 32 g/cm3 fine gold will deposit at the corner of the river slow flow rate forming the placer gold deposit where you looking for The actual formation of geological structures varies widely River gold is generally in the sand layer and not in the rocks
