Extracting Gold | HowStuffWorks
As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon. Filtering the pulp through screens separates the gold-bearing carbon. The carbon moves to a stripping vessel where a hot caustic solution separates the gold from the carbon.
How is Gold Formed and Where Does Gold Come From?
Pulled together by gravity, hydrogen atoms slam together to form helium atoms, which release enormous amounts of energy in the form of heat and light. Eventually, the hydrogen in the star's core runs out, and gravity causes the star to collapse. What happens next depends on the star's mass, but gold is formed when the collapse creates …
