Gold and climate change: An introduction World Gold Council

Gold is rare and, as with other precious metals, a lot of ore is mined and processed to produce small amounts of pure metal. The gold production process therefore uses a relatively high level of energy to bring finished gold to market and has a higher greenhouse (GHG) emissions intensity per tonne of finished product than many other bulk metals.

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.
