Leaching dissolves the gold out of the ore using a chemical solvent. Themon solvent is cyanide, which mustbined 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.
