    Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent iscyanide,which must be combined with oxygen in a process known as carbon-in-pulp. As thecyanideand oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.
