A sluice box separates gold from sand and gravel as the gold catches on the ridges in the bottom.
No. One can not transform one element into another. However Mercury may be used to extract gold from gold containing sand. The gold will dissolve in the mercury which can then be boiled away to leave the gold. This will APPEAR to make mercury change into gold but this is not the case, you have to put the gold into the mercury first.PLEASE NOTE - Mercury is VERY VERY toxic/poisonous and using it to extract gold this way is dangerous to the environment and harmful to the people doing it (especially the boiling away mercury phase) - do not refine gold this way, use a mechanical separation process.
Mercury
Gold is particularly attracted to mercury. In fact, mercury is used to extract gold from the ore that it is found in. Then a cyanide is used to make the mercury 'let go' of the gold in a manner in which people can recover it.
wheat. The process is known as willowing and separates the wheat from the chaff. Gold. The process is known as panning and separates the gold from silt. uranium. The process is known as enriching and separates the docile U238 from the nasty U235
Mercury and gold are two different elements. There is no mercury in gold and there is no gold in mercury. If there is some gold mixed in with the mercury to begin with, then there are ways to separate it out. If there is no gold in the mercury to begin with, then there's no way to get any gold out of it.

Gold is more dense than mercury
gold: 79 mercury: 80

== == A machine invented by Eli Whitney that separates cotton fibers from the seedpods. It is an easier way than separating the fibers from the pod by hand.
At one time, mercury WAS used to extract gold from gold ore. The rock was crushed, and washed over a copper sheet coated with mercury. Gold forms an amalgam with mercury, and some of the gold would be trapped in the mercury. The mercury would be scraped from the copper, and distilled, leaving behind the gold. Other processes are used today.
Gold is a higher density than Mercury so it will sink if placed into a container of mercury.

Mercury was used to dissolve gold from the ore. The mercury/gold mixture was then heated to drive off the mercury leaving the gold. The mercury vapours were detrimental to the environment and the jhealth of the prospectors
