How is gold made? UCSB Science Line

Wohlwill's process is based on the solubility of gold, but the insolubility of silver, in an electrolyte solution of gold chloride (AuCl 3) in hydrochloric acid. The impure gold is cast into anodes of about 100 ounces each, which are suspended in porcelain cells, while the cathodes are thin strips of pure gold.

How Is Gold Formed and Where Does it Come From ...

Gold isn't truly formed—at least, not on Earth. Gold Comes From Outer Space. Gold, the shiny yellow metal prized for its beauty and malleability and used in many different industries, is actually created inside massive stars when they explode into a supernova. Of course, after a star supernovas and forms gold, the precious metal has to travel to Earth in some way.
