they fire a laser into the minerals containing the gold compounds. The laser is exactly tuned to to the frequency that gold radiates and the result is that molten gold drains out of the rock. The liquid is then caught under a machine called a PPSH-41 bicarbonate diaphragm and is then synthesized into a sedamediphine that will then be cooled to approx. room temperature. Then process is then repeated until the gold emimits reflective radiate energy equal or greater than the frequency of the original laser.
Impure gold is first dissolved, along with the other metals in aqua regia. This forms chlforoauric acid. The gold is then precipitated out with sodium metabisulfite or oxalic acid. The precipitate is pure gold. This is then melted into bard or another gold shape.
using Mercury. Also gold can be recovered by treating the gold ore with with a solution containing cyanide.
It is far less reactive to acids or oxidation processes; i.e., it is relatively inert except to binary acids or special chemical processes.
Gold is isolated from other material through mechanical and chemical processes. Gold is non-magnetic, so a magnetic material is easily taken away.
Gold is generally separated from rocks with sodium cyanide.
With the element mercury.
Extracted insulin is usually purified by recrystallisation from solutions in the presence of ZnCl2.
It is purified by heating or Chemical exposure.
Mercury is extracted from cinnabar by heating and collecting the vapors. In factories, the rock is ground up into a fine powder which is then heated.
0.417 mol could be extracted.
100 years ago gold was quite simply panned for in river beds. Also it was mined by hand, miners used to seek a gold seam. Gold mines now use advanced mechanical tools to recover material that gold may be in. Gold can now be extracted from these materials by chemical methods.

its extracted from the ancient baya tree, found in the hill tops of the himalayas. And purified by meow mix cat food
Well, you have to get them from someplace. They have to be extracted from the ground before they can be processed.
mineral
It is purified by heating or Chemical exposure.
Metal cannot be extracted from Gold, as Gold itself is a metal.
Mercury is extracted from cinnabar by heating and collecting the vapors. In factories, the rock is ground up into a fine powder which is then heated.
transistor are materials they have to be extracted and purified this relies on chemistry and material science
it gets turned into our everyday life utesils
