May 06, 2019 It's only accessible today because of asteroid bombardment. 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.

Gold electrolysis requires small amount of chemicals and labor. It is, in fact, environmentally friendly. However, it is a very expensive procedure because a permanent stock of gold is required to run the electrolytic process. Take for instance, for every gold produced through this method, 20% of it is lost on the anode.

Mar 29, 2020 Gold is processed by cyanide milling, a chemical procedure that separates 95 to 98 percent of the gold from raw mined ore. It is then refined to the gold standard purity, according to Mineweb. Heap leaching is a less expensive method of gold extraction, but it is a longer process and it recovers less gold than the cyanide milling process.
