Extracting Gold | HowStuffWorks
The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. 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. ... In electrowinning, operators pour the gold-bearing solution into a ...
