chemicals for extracting gold
Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide which must be combined with oxygen in a process known as carboninpulp. 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.
