How Is Gold Formed? Origins and Process

06-05-2019  Theoretically, it's possible to form gold by the nuclear processes of fusion, fission, and radioactive decay. It's easiest for scientists to transmute gold by bombarding the heavier element mercury and producing gold via decay. Gold cannot be produced via chemistry or alchemy. Chemical reactions cannot change the number of protons within an atom.

How Is Gold Formed? Origins and Process

06-05-2019  Since gold is heavy, it sinks and accumulates in stream beds, alluvial deposits, and the ocean. Earthquakes play an important role, as a shifting fault rapidly decompresses mineral-rich water. When the water vaporizes, veins of quartz and gold deposit onto rock surfaces. A similar process occurs within volcanoes.

Gold mining - Wikipedia

Gold panning is mostly a manual technique of separating gold from other materials. Wide, shallow pans are filled with sand and gravel that may contain gold. The pan is submerged in water and shaken, sorting the gold from the gravel and other material. As gold is much denser than rock, it quickly settles to the bottom of the pan.
